How do the guard cells regulate the opening and closing of stomatal pores?
Answers (1)
Guard cells regulate the opening and closing of the stomatal pores by changing water volumes through swelling and shrinking with the process of osmosis.
- Opening- Guard cells will swell by absorbing water that enters and opens the pores. Here, guard cells are said to be turgid.
- Closing- During flaccid conditions, the stomatal aperture closes. Here, guard cells lose water and shrink up.
