What happens when sugar is converted into starch in guard cells?
Open in App
Solution
Conversion of starch:
When sugar is converted into starch in guard cells, the stomatal pores completely close.
Carbon dioxide liberated during the process of respiration gathers during the nighttime.
The guard cell’s acidity increases while the pH decreases.
The decreased pH promotes the sugar to starch conversion.
There is a decrease in the pressure of guard cells as a result, they turn flaccid thus, closing the stomatal aperture.
