Correct option is D
The correct option is (D) A root cap participates in the process of transpiration.
Explanation:
The root cap primarily serves as a protective structure at the tip of the root. It helps in the easy movement of the root through the soil, protects the delicate root tissues, and plays a role in gravity perception. However, it does not participate directly in transpiration, as transpiration occurs mainly through the stomata in the leaves, not in the root cap.
Information Booster:
Root cap helps in lubricating the root tip, enabling it to move through the soil more efficiently.
It contains cells that secrete mucilage, which reduces friction as the root grows and penetrates the soil.
The root cap also plays a crucial role in gravitropism, helping the plant sense gravity and grow downward.
The root cap protects the meristematic tissues of the root, which are responsible for root growth.
Transpiration:
Transpiration is the process of water loss primarily through the stomata of leaves and stems, not from the root cap.
The main function of the root is water and nutrient absorption, while transpiration helps in cooling the plant and maintaining water flow.
Gravity Perception:
The root cap contains statocytes, specialized cells that contain amyloplasts, which help the root sense gravity and ensure proper downward growth.
