Question 10

When guard cells are flaccid, the stoma must be:

  1. Open
  2. Neither open nor closed
  3. Closed
  4. None of these
Answer

Closed

Reason — When guard cells are flaccid, their inner wall is relaxed closing the stomata. Similarly, when the guard cells become turgid the inner wall is pulled outwards opening the stomata.
