The function of the root cap is (a) Protection of root tip and control of geotropic movement(b) Storage of food products (c) Absorption of nutrients(d) None of the above

The correct answer is (a) Protection of root tip and control of geotropic movement.

Explanation:

The root cap is a specialized structure at the tip of a plant's root. Its functions include:

Protection of the root tip: The root cap protects the sensitive apical meristem (growth region) of the root from mechanical damage as the root pushes through the soil.

Control of geotropic movement: The root cap helps the root sense gravity, allowing the root to grow downward in the soil in response to gravity, a process known as geotropism (or gravitropism).

Thus, the root cap is involved in both protecting the root tip and helping the root grow in the proper direction, in response to gravity.

The other options (b, c, and d) are not related to the function of the root cap.
