MCQs on Internal Structure of Root System and Leaf

1. The root system is responsible for anchoring the plant to the soil and absorbing water and minerals from the soil.

2. The root system consists of a main root (the taproot), which grows downwards, and a number of smaller lateral roots, which grow outwards from the main root.

3. The root system is surrounded by a tough protective layer of cells, called the root cap.

4. The root cap protects the delicate root tissues from damage, and also helps the root to penetrate the soil.

5. The root system is supplied with nutrients and water by the stem of the plant.

6. The stem of the plant also transports food produced by the leaves to the rest of the plant.

7. The leaves are responsible for photosynthesis, which is the process of converting sunlight into energy.

8. The leaves are also responsible for gas exchange, which is the process of exchanging gases between the plant and the environment.

9. The leaves are attached to the stem of the plant by a stalk.

10. The leaves are arranged in a spiral pattern around the stem.
