Question

Turgidity of guard cells leads to opening of stomata.

• A. True
• B. False

Answer 1

The correct option is A True

1. The outside thick walls of the guard cells stretch out as the turgidity inside the guard cells rises. This exerts a force on the inner walls of the guard cells, causing them to become crescent-shaped and stomata to open.
2. The inner walls of the guard cells regain their original size when their turgor is lost due to water loss. The guard cells become flaccid, causing the stomata to close.

The given statement is true.
