Worksheet / Test Paper
Answer each question below related to parts of plant and animal cells & their functions based on the clues given.
1. It provides shape to the cell. It is semi-permeable, regulating the entry and exit of substances, namely solutes and
ions.
Answer:
2. It provides protection, shape and rigidity to the cell. It is freely permeable, allowing substances in the form of
solutions to enter and leave the cell without any hindrance.
Answer:
3. It initiates and regulates cell division. It also helps in forming spindle fibres, with the help of asters.
Answer:
4. It is a plastid, containing a pigment called chlorophyll. This chlorophyll captures energy from sunlight and helps in the
manufacture of food by the process of photosynthesis.
Answer:
5. It is a plastid, containing pigments such as xanthophyll (yellow in color) and carotene (orangish-red in color). These
pigments impart color to flowers and fruits of plants.
Answer:
6. It is the house of all metabolic activities and functions in the cell. In other words, it contains most of the cell
organelles, each of which perform a specific function.
Answer:
7. It provides support to the cell. It also helps in the synthesis and transport of proteins and fats.
Answer:
8. It synthesizes and secretes certain substances, namely hormones and enzymes. It also helps in the formation of
acrosome of sperm.
Answer:
9. It is a plastid. It helps in the storage of starch.
Answer:
10. It performs intracellular digestion. It also helps in destroying foreign substances.
Answer:
11. It is the site of ATP (Adenosine triphosphate) synthesis. It also synthesizes respiratory enzymes.
Answer:
12. It is semi-permeable, allowing substances to enter and leave the nucleus of the cell. It also provides protection to the
nucleus of the cell.
Answer:
13. It synthesizes proteins by producing and storing RNA (Ribonucleic acid). At the same time, it orders ribosomes to
synthesize proteins.
Answer:
14. It contains chromatin fibres, which are made up of DNA (Deoxyribonucleic acid). After cell division takes place, these
chromatin fibres undergo certain structural changes, and are called chromosomes. These chromosomes carry the
hereditary information of the genes.
Answer:
15. It controls and coordinates all the activities and functions of the cell. It plays a vital role in cell division.
Answer:
16. It is known as the 'site of protein synthesis in the cell', and synthesizes proteins. It is chiefly composed of RNA
(Ribonucleic acid).
Answer:
17. It helps in the storage of water and several other substances, namely food, waste products and pigments. It also
provides turgidity to the cell.
Answer:
