What is the role of the root cap?
Root cap:
1. The root cap is a small tissue at the tip of the root, that protects the root from environmental stress and functions in gravity perception.
2. Root caps are thimble-like structures covering the apex of roots.
3. It renders protection to the tender apex of roots as it makes its way to the soil.
4. Root cap is also called calyptra.
Role of root cap:
1. The role of the root cap is to protect the root tip and control geotropic movement.
2. Root caps contain statocytes which help in gravity perception in plants.
3. The root cap is also involved in the protection of the growing tip in plants.
4. It secretes mucilage to ease the movement of the root through the soil and may also be involved in communication with the soil microbiota.
