Question

The function of root cap is to

• A. Protect the root tip
• B. Protect the root hairs
• C. Cover the root
• D. Growth of the root

Answer 1

The correct option is A Protect the root tip

• At the terminal region of the root tip is a cup-like or a thimble-like structure called the root cap which is formed from calyptrogen (specialized internal meristematic cells).
  
• It is also known as calyptra.
  
• It contains statocytes which help in gravity perception in plants that help in the growth of root towards the soil.
  
• The root apex is protected by this root cap as it penetrates into the soil.
  

The root cap is formed by a specialized internal meristematic which is part of the histogen and is called calyptrogen

So, the correct answer is 'Protect the root tip'
