Text Solution

Verified by Experts

The correct Answer is:
B
Guard cells help in transpiration. Stomata are surrounded by two specialised epidermal cells, called guard cells. Because of their small size guard cells are repidily influenced by turgor changes and thus regulate the opening and closing of stomata. Stomata are involved in releasing water vapour into the atmosphere. This process is known as transpiration.
