Solved Questions For You:

Question 1. A baby is not able to tell her/his caretakers that she/he is sick. What would help us to find out?

(a) That the baby is sick? (b) What is the sickness?

Question 2. Under which of the following conditions is a person most likely to fall sick?

(a) When she is recovering from malaria. (b) When she has recovered from malaria and is taking care of someone suffering from chicken-pox. (c) When she is on a four-day fast after recovering from malaria and is taking care of someone suffering from chicken-pox. Why?

Answer: A person is more likely to fall sick when she is on a four-day fast after recovering from malaria and is taking care of someone suffering from chickenpox. This is because since she has suffered from malaria and is in the recovery phase, it means that she is still not completely diseases-free. Fasting affects the immune system as the body is deprived of essential nutrients required to maintain a healthy body. Chickenpox is a contagious disease, this also makes her susceptible to contracting the disease while taking care of a person suffering from chickenpox.

Question 3. A doctor/nurse/health-worker is exposed to more sick people than others in the community. Find out how she/he avoids getting sick herself/himself.

Answer:  Medical personnel are constantly in contact with the sick and diseased people coming in the hospitals for the treatment. They follow various measures in order to prevent themselves from getting infected:

Access NCERT Solutions for The Fundamental Unit of Life Class 9

1. Who discovered cells and how?

Ans: The dead cells were first discovered by Robert Hooke in 1665. He observed in cork cells that the cells are like honeycomb structures with the help of a basic microscope while the living cells were first discovered by Antoine van Leuwenhoek after the discovery of the electron microscope.

2. Why is the cell called the structural and functional unit of life?

Ans: Cell is the basic unit of life and is present in all living organisms. Each living cell performs its specific functions that are the characteristics of all living forms. The cell consists of various cell organelles which help the cell to live and perform all its functions. The various cell organelles perform their special function that includes making new material in the cell, removal of the waste material from the cell and so on. Thus, cells are called basic structural and functional units of life as they perform all these functions.

3. How do substances like $\mathbf{CO_2}$ and water move in and out of the cell? Discuss.

Ans: By the process of diffusion the substances like carbon dioxide and water move in and out of a cell from the region of high concentration to the region of low concentration. When the concentration of carbon dioxide and water is higher outside the cell than carbon dioxide and water moves inside the cell and when the concentration of carbon dioxide and water is lower outside the cell and is higher inside the cell then they move out of the cell.

4. Why is the plasma membrane called a selectively permeable membrane?

Ans: The plasma membrane or the cell membrane is known as a selectively permeable or semipermeable membrane because it is responsible for the regulation of the various substances in and out of the cell. This results in the entry of certain substances and inhibits the entry of other substances through the plasma membrane.

5. Fill in the gaps in the following table illustrating differences between prokaryotic and eukaryotic cells.

6. Can you name the two organelles we have studied that contain their own genetic material?

Ans: The two organelles we have studied that contain their own genetic material are mitochondria and plastids. Mitochondria help in respiration in the cell while plastids are responsible for the process of photosynthesis in leaves.

7. If the organization of a cell is destroyed due to some physical or chemical influence, what will happen?

Ans: If the organization of a cell is destroyed due to some physical or chemical influence then the cell will not be able to perform many basic functions like photosynthesis, respiration, nutrition, etc., and may also result in the stopping of all life activities in the cell. Due to the cell damage, the lysosome bursts, and their enzymes digest such cells.

8. Why are lysosomes known as suicide bags?

Ans: Lysosomes are the cell organelles that are vesicular structures and contain the digestive enzymes. The function of these enzymes inside the lysosomes is to break down any foreign body that enters the cell. Sometimes, the lysosome may also act suicidal by releasing the digestive enzymes inside the cell and leads to self-destruction. Thus lysosomes are known as suicidal bags.

9. Where are proteins synthesized inside the cell?

Ans: Proteins are the building blocks of the body that are made up of various amino acids. They are synthesized inside the ribosomes that are the small structures present in the cytoplasm or might be attached to the surface of the endoplasmic reticulum. The endoplasmic reticulum is called the rough endoplasmic reticulum due to the presence of ribosomes on its surface. 

10. Make a comparison and write down ways in which plant cells are different from animal cells.

Ans: The difference between the plant cells and the animal cells are:

11. How is a prokaryotic cell different from a eukaryotic cell?

Ans: The difference between a prokaryotic cell and a eukaryotic cell are:

12. What would happen if the plasma membrane ruptures or breaks down?

Ans: The function of the plasma membrane is to act as a semipermeable membrane and regulate the entry and exit of the various substances in and out of the cell by the process of diffusion or osmosis and if the plasma breaks or ruptures then the contents of the cell might leak. This will result in the cells getting less nutrition than required.

13. What would happen to the life of a cell if there was no Golgi apparatus?

Ans: The function of the Golgi apparatus is packaging and transferring substances from one part of the cell to another. If the Golgi apparatus is absent in a cell then packaging of the proteins or the arrangement of the structural protein will not take place inside a cell. Proteins are essential for cells to perform various metabolic functions and if the proteins fail to reach the cell then this metabolism in the cell will not take place and eventually this will cause the cell to die.

14. Which organelle is known as the powerhouse of the cell? Why?

Ans: Mitochondria are known as the powerhouse of the cell as they produce the energy which is required by the cell to perform various functions. The energy which is released by the mitochondria is in the form of ATP molecules and is required for various chemical activities needed for. The energy stored in ATP is used by the body to make new chemical compounds and to perform mechanical work. Thus, mitochondria are known as the powerhouse of cells.

15. Where do the lipids and proteins constituting the cell membrane get synthesized?

Ans: Lipids and proteins are the essential part of the plasma membrane which is synthesized through the endoplasmic reticulum. The endoplasmic reticulum is found to be of two types based on the substances they synthesize. The smooth endoplasmic reticulum is responsible for the synthesis of lipids while the rough endoplasmic reticulum is responsible for the synthesis of proteins.

16. How does an Amoeba obtain its food?

Ans: Amoeba contains pseudopodia which are responsible for engulfing as well as removing food. The process by which amoeba acquires their food is called endocytosis. The plasma membrane of the amoeba is quite flexible thus enabling the cell to engulf the food particles and other materials from its external environment and also excrete the waste outside through the process called exocytosis.

17. What is osmosis?

Ans: The process of movement of water molecules from a region of high water concentration to a region of low water concentration through a selectively permeable membrane is called osmosis. This process continues until the solute concentration reaches equilibrium. The movement of water takes place across a concentration gradient to maintain equity on both sides of the cell.

18. Carry out the following osmosis experiment:

Take four peeled potato halves and scoop each one out to make potato cups. One of these potato cups should be made from a boiled potato. Put each potato cup in a trough containing water. Now,

Keep cup A empty

Put one teaspoon sugar in cup B

Put one teaspoon salt in cup C

Put one teaspoon of sugar in the boiled potato cup D.

Keep these for two hours. Then observe the four potato cups and Solution the following:

(i) Explain why water gathers in the hollowed portion of B and C.

(ii) Why is potato A necessary for this experiment?

(iii) Explain why water does not gather in the hollowed-out portions of A and D.

Ans: The Solutions Are as Follows:

(i) The concentration of water that surrounds the potato is found to be more than inside which results in the flow of water inside the potato by the process of osmosis. Thus, the water gathers in the hollowed portions of setup B and C.

(ii) Potato A in this experiment is necessary since it is kept as a control set-up that helps in comparing the changes that have taken place in the other two setups of the experiment. By this, we can easily detect the changes in the different setups.

(iii) Since there is no change in the concentration of water in cup A so the water will not gather in the hollowed-out portions while in the case of cup D, due to boiling plasmolysis has taken place which leads to the absence of osmosis thus here also the water will not gather in the hollowed-out portions.

FAQs on NCERT Solutions for Class 9 Chemistry Chapter -5 The Fundamental Unit of Life

1. What do Osmosis and Diffusion mean as per the fundamental unit of life class 9?

Osmosis is a process through which water moves in and out of the cell membrane. The movement is always from a region of higher concentration to lower concentration of water through a selectively permeable membrane until it reaches an equilibrium.

In a similar manner, diffusion refers to the process by which Carbon Dioxide moves in and out of the cell membrane. The cellular wall contains a high level of CO 2 , whereas the CO 2 concentration outside is significantly low. This causes the CO 2 to move from a region of higher concentration to that of low concentration to maintain a level of equilibrium.

2. What are the important topics in the Fundamental Unit of Life as per the NCERT Solutions?

The important topics that students must learn in the chapter fundamental unit of life are – Discovery of the cell, Unicellular organism, Multi-cellular organism, characteristics of the cell, structural organization of cell-like plasma membrane, nucleus, and cytoplasm, DNA, Chromatin material, Chromosomes, and proteins.

Apart from this, students must also focus on topics like Mitochondria, Plastids, lysosomes, chloroplast, leucoplast, vacuoles, Golgi apparatus, Ribosomes, Endoplasmic reticulum, and Cell organelles. Students should focus on learning the topics extensively. Diagrams of every structure and its parts should be learned in detail to answer MCQ, long answer and questions based on diagrams.

3. What is the difference between Prokaryotic and Eukaryotic cells as per the NCERT Solutions?

There are four main differences between Prokaryotic and Eukaryotic cells, which are largely related to their structures and size.

Prokaryotic cells are smaller in size, but Eukaryotic cells are bigger in general. The nucleoid is the nuclear portion of a prokaryotic cell that lacks a nuclear membrane. In comparison, the nuclear membrane of a Eukaryotic cell is strongly defined. Prokaryotic cells have a single chromosome, whereas Eukaryotic cells have many chromosomes. Membrane-bound cell organelles are not found in prokaryotic cells, but they are present in eukaryotic cells. Vedantu ch 5 science class 9 provides best practices to crack the exams.

DePaul University fires biology professor over assignment about Israel-Hamas war

Anne d’aquino’s assignment ‘negatively affected the learning environment,’ chicago school says.

Rep. Nancy Mace on anti-Israel protests: 'This isn't 1940's Germany'

Rep. Nancy Mace, R-S.C. weighs in on President Biden's trip to France, the administration urging Hamas to accept a cease-fire deal with Israel and her expectations for the G-7 summit.

DePaul University says it has fired a part-time biology professor after she gave an optional assignment to students last month asking them to write about the impact of "genocide in Gaza on human health and biology." 

An investigation into the assignment offered by Anne d’Aquino "found it had negatively affected the learning environment by introducing extraneous political material that was outside the scope of the academic subject as outlined in the curriculum," according to the school. 

"The class was provided a new instructor, and the faculty member has been released from their appointment as a part-time faculty member," DePaul University said in a statement to The Associated Press, adding that some students "expressed significant concern" about politics in a science class on how microorganisms cause disease. 

The Chicago-based school also said an email with the assignment showed support for people "resisting the normalization of ethnic cleansing." 

Around the same time, DePaul administrators were grappling with an anti-Israel encampment on campus.

D’Aquino is appealing the decision, saying during a student demonstration on campus in support of her last Thursday, "My termination was a breach of my academic freedom and another example of this administration’s efforts to twist any discussions of Palestine and Palestinian liberation language into false claims of antisemitism."  

D’Aquino was teaching Health 194, Human Pathogens and Defense in early May, according to CBS Chicago.  

In its online academic catalog, DePaul describes the course as introducing students "to the diverse microorganisms that cause significant disease within the human population." 

"The biological basis of infectious disease will be explored with a focus on the mechanisms of viral and bacterial infection and spread," the course description adds. "The principles behind tools used combat infection will be examined, including antiseptics, antibiotics/antivirals, and vaccination."

(AP/Abdel Kareem Hana)

DePaul University said in a statement to Fox News Digital on Monday that "The faculty member has initiated an appeal, as is her right under the Faculty Handbook" and "That process is currently underway and will be completed soon."

D’Aquino did not immediately respond Monday to a request for comment from Fox News Digital, but she said last week at the rally, "My case is a reminder that if faculty and staff are not protected from the swift and severe reprimand of this university, students most certainly are not either."

"The assignment was, in fact, related to the course and its objectives," D'Aquino also said.

DePaul University Fires Biology Professor For Israel-Hamas Class Assignment

CHICAGO (AP) — DePaul University said it dismissed a part-time biology instructor after she gave an optional assignment related to the Israel-Hamas war.

Anne d’Aquino told students in May that they could write about the impact of “genocide in Gaza on human health and biology.” The theme of the spring class at the Chicago school was how microorganisms cause disease.

DePaul said some students “expressed significant concern” about politics in a science class.

“We investigated the matter, spoke with the faculty member, and found it had negatively affected the learning environment by introducing extraneous political material that was outside the scope of the academic subject as outlined in the curriculum,” DePaul said Friday in a statement.

The school noted an email with the assignment expressed support for people “resisting the normalization of ethnic cleansing.”

“The class was provided a new instructor, and the faculty member has been released from their appointment as a part-time faculty member,” DePaul said.

D’Aquino is appealing her dismissal.

About 50 people protested last Thursday in support of her, waving Palestinian flags, the Chicago Sun-Times reported.

“My termination was a breach of my academic freedom and another example of this administration’s efforts to twist any discussions of Palestine and Palestinian liberation language into false claims of antisemitism,” d’Aquino said at the demonstration.

She said the assignment was relevant, noting that scientists have warned about the spread of disease in Gaza due to malnutrition and a lack of water and adequate sanitation.

CBSE Class 9 Science Practicals

CBSE Practicals of Class 9 Science are equally important as the theory subject. By performing the practicals, students will learn by actual participation, which lasts in their memory for a longer time. Generally, most students forget the concepts that they have learnt in theory classes. But, when they perform the Science practicals, they remember it for a longer period. We easily forget the things that we listen to, but what we see remains firmly etched in our memory. Therefore, the CBSE Board has introduced practicals for Science subjects in Class 9. Here, we have provided all the details of Class 9 Science CBSE practicals for students.

Science practicals not only help students to understand the concepts but also generate interest among them. They get a platform to try out different things and showcase their creativity. In this way, their love for Science also gets enhanced. Moreover, students who find Science difficult also begin taking an interest in the subject.

CBSE Class 9 Science Practicals – Syllabus, Lab Manual and Kit

The CBSE Board has provided the official syllabus for Class 9 Science practicals. Also, the Board has allocated 30 periods for conducting all the practicals.  Here, we have provided a list of Science experiments that students need to perform in the laboratory. Further, we have also provided the information on the lab manual, important questions asked in practical exams and NCERT Science manual kit.

CBSE Class 9 Science Laboratory Manuals

Students performing experiments by themselves will get a thrilling experience as they learn by participating. All the experiments are performed in the school Science laboratory. So, students must be aware of certain rules and regulations before performing experiments in the laboratory. For this purpose, the CBSE Class 9 Science lab manual has been provided by the Board. The laboratory manual familiarises students with the general facilities, chemical and glassware, measuring instruments, equipment, and specimen available in a school Science laboratory. The lab manual also mentions the precautions and safety measures mandatory for students to follow.

The description of the experiment in the CBSE Class 9 Science laboratory manual is provided in the following format:

• Aim of the experiment.
• Theory or the principle involved in the experiment.
• List of materials required to perform the experiment.
• Steps to be followed while performing the experiment.
• Recording the observations.
• The formula required for calculations and, finally, recording the result of the experiment.

CBSE Class 9 Science Practical Important Questions

Here, we have listed a few questions from the CBSE Class 9 Science manuals. These questions are related to Physics, Chemistry and Biology topics of Science. However, students will get all these questions in the PDF files, which are provided above. Besides, at the end of each experiment, a few questions are provided in the lab manual.

Q1) A 100 g block slides when tension in the string is x N. What will be the tension in the string when an identical block is placed at the top of the first block?

Q2) State the factors on which the buoyant force acting on an object immersed in a fluid depends.

Q3) What will happen if a de-shelled egg is placed in a solution with the same osmotic concentration as in the egg?

Q4) What are the conditions that are helpful for the breeding of mosquitoes?

Q5) A metal cylinder is melted, and the whole mass is cast in the shape of a cube. What happens to its density? Give reasons.

Q6) What different techniques of separation can be employed for the separation of components of a homogeneous and heterogeneous mixture?

NCERT Class 9 Science Manual Kit

The NCERT Class 9 Science manual kit describes the kit items and their uses. It contains the activities of NCERT Class 9 Science textbook. Also, the experiments that are provided can be performed using this kit. The NCERT textbooks are designed in such a way that it covers various activities. In each chapter, topics are explained with the help of these activities. Just merely reading through the textbook will not help students to understand the concepts explained. It is required that students perform these activities. This can be done through the NCERT manual of the Class 9 Science kit. Performing these activities will enable students to think and explore. This will inculcate the questioning ability, exploring and discovering Science facts, which will create interest towards scientific discovery in students.
