Question

Explain the mechanism of opening and closing of stomata according to K* ion transport
mechanism.
​

Answer 1

Answer:

Due to higher concentration of the cytoplasm of guard cells, the water comes to them from the neighbouring cells by osmosis and they become turgid. With the result the stomata remain open. In the night or in the absence of light the sugar present in guard cells converts into the starch.

Answer 2

Answer:

stomata opens when concentration k+ ion is more and close when k+ ion is less and also depends on the environmental conditions.
