If Levitt's hypothesis is to be believed, then the opening and closing of stomata take place as a result of ______ in and out of guard cells.
Options:
Answer:
B
Solution:
According to Levitt's proton pump theory entry of potassium ions in the guard cells from surrounding epidermal cells in exchange of protons, causes opening of stomata. This exchange of protons and potassium ions requires energy and thus is an active process. Increase in potassium ions, increases the osmotic concentration of guard cells causing endo-osmosis. This makes the guard cells turgid causing opening of stomata
