Question

State whether the following statements are true/false. Rewrite the false statements after correction.​

​(v) Opening and closing of stomata is due to turgidity

• A. True
• B. False

Answer 1

The correct option is A True

Answer: True.​

• ​A stomata opens and closes in response to the internal pressure of two sausage-shaped cells called 'guard cells' that surround it. ​

• The inner wall of a guard cell is thicker than the outer wall.​

• When the guard cell is filled with water and it becomes turgid, the outer wall balloons outward, drawing the inner wall with it and causing the stomate to enlarge and open.​

• When the guard cells lose their turgor due to water loss, the inner walls gain their original size. The guard cells become flaccid resulting in the closing of the stomata.
