Answer 2

Answer:

Opening and closing of stomata depends upon turgidity and flaccidity of surrounding guard cells.

When the guard cells fill up with water, they are said to become turgid. They swell to provide a stomatal pore through which gas exchange occurs. When the guard cells lose water, they become flaccid and the pores close( usually at night, except in desert plants ).
