Look at the diagram of a cell in Fig. Identify the parts labelled from (a) to (g). Class 9
Question 1.
Look at the diagram of a cell in Fig. Identify the parts labelled from (a) to (g) and correctly match them with their functions given below: Class 9
(i) Controlling all the activities of a cell.
(ii) Site of cellular respiration.
(iii) Storage organelle that also provides rigidity to the cell.
(iv) Separates the cell contents from surroundings.
(v) Provides structural rigidity to the cell.
(vi) Packs and stores materials received from ER.
(vii) Helps in manufacturing food.
Answer:
Based on a typical plant cell diagram, the labels and their matching functions are:
| Label | Organelle | Functions |
| (a) | Mitodondria | (ii) Site of cellular respiration. |
| (b) | Nucleus | (i) Controlling all the activities of a cell. |
| (c) | Golgi Apparatus | (vi) Packs and stores materials received from ER. |
| (d) | Chloroplast | (vii) Helps in manufacturing food. |
| (e) | Cell wall | (v) Provides structural rigidity to the cell. |
| (f) | Cell membrane | (iv) Separates the cell contents from surroundings. |
| (g) | Vacuole | (iii) Storage organelle that also provides rigidity to the cell. |
Question 2.

Answer:
| Option | Present in the plant cells | Present in the plant cells | Correct/ Incorrect |
| (i) | Leucoplast | Cell wall | Correct |
| (ii) | Mitochondria | Ribosome | Incorrect |
| (iii) | Cell wall | Golgi apparatus | Incorrect |
| (iv) | Lysosome | Endoplasmic reticulum | Incorrect |
