Question: 2. Which organelle would you not find an animal cell and why do they need it?

Answer: Chloroplast is the organelle that we find in plant cells but not in the animal cell. It works as a food making machine because it has chlorophyll (a substance that makes plants green) which converts sunlight energy into sugar or chemical energy which is used by the plant.

For example; Protozoa, Unicellular algae and unicellular fungi, etc,.

Question: 16. Write some Features of cells.

Answer: Following are the features of cells:

1. Plasma: It is the pipe of a cell, through which passing going and coming of material takes place.

3. Nucleus: It contains the Genetic properties of a cell which is fundamental to any cell.
4. Plastids: it changes the reaction processes with the help of chlorophyll.
6. Mitochondria: these are biochemical processes of respiration and energy production occur.

Question: 17. Full form of ATP?

Answer: Adenosine triphosphate, an energy reactor.

Question: 18. What is the other name of plasma?

Answer: Membrane or cell membrane

Question: 19. Can you name some functions of Plasma?

1. It support structural base
2. works as a sender of material from outside to inside or vice-versa, act as receptor sites
3. Carrier of molecules
4. Provide information of identification markers
5. It creates "diffusion" of water and gases in both cells like hypotonic solution, isotonic solution and hypertonic solution.

Question: 20. What are two types of endoplasmic reticulum?

Answer: There are:
1. RER : Rough Endoplasmic Reticulum
2. SER : Smooth Endoplasmic Reticulum

Question: 21. Write the full form of DNA.

Answer: Deoxyribonucleic acid

Questions of Plant and Animal cell

Question: 22. Write the full form of RNA

Answer: Ribonucleic acid

Question: 23. Explain nucleus.

Answer: Nucleus is the fundamental base of the cell and has chromatic thread-like structures which contain DNA.

Question: 24. Describe a nuclear membrane.

Answer: Nuclear membrane has outer double layer which are as follows:
1. Chromosomes
2. Nucleotide

Question: 25. What is Chromosome?

Answer: They are rod-like structures, containing DNA and protein.

Question- 26. What is Nucleotide?

Answer:The part of the nucleus in which nucleic acid is present is called Nucleotide.

Question:27.What is Cytoplasm?

Answer: Cytoplasm refers to "cyto" means cell and "plasm" means liquid, the liquid which is present in a cell is called cytoplasm. It is a mixture of water, salt, and protein. Organelles each of these perform specific activity for the cell. Their arrangement of fine fibers in a complex situation.

Question:28. Explain the function of cytoplasm.

Answer: It works:
1. cellular expansion
2. growth and replication by diffusion.

Question: 29. What is organelles?

Answer: Some specific components in a cell , which performs different functions are called organelles. For example: mitochondria, ribosomes, endoplasmic reticulum, golgi apparatus and lysosomes.

Question: 30. What is Golgi Apparatus?

Answer: It is a connector of things or products which are present in a cell to Endoplasmic Reticulum, therefore moving from one side to another. It acts as storage, modification and packaging of products in vesicles.

Question: 31. Give reasone for suicide bags to be called?

Answer: The work of lysosome is to clean the cell from inside by elimination of wastage. During these alterations in a cell's metabolism When a cell is damaged, lysosomes can explode and enzymes digest their own cells. So, these are called "suicide bags".

Question: 34. What is the difference between a cell wall and cell membrane?

Answer: Cell membrane is outer membrane and fragile It controls the passage of coming and going out of the cell. The plasma membrane is made up of phospholipid bilayer, embedded proteins and some carbohydrates. On the other side, Cell wall is generally permeable, it is non-living and quite thick in plant cells, it is formed of cellulose,hemicellulose and pectin, and which supports and protects the membrane.
