Homeostasis may be defined as the ability of the living organisms to maintain the internal physiological environment in response to the internal and external stimulus. Humans, plants and other living organisms shows the homeostasis mechanism.
Stomata are the small opening present in the leaves that helps in the exchange of gases and water. The hot dry day causes the stomata to remain in closed state so that water can be prevented and reduces the dehydration or loss of water in plants. This maintains the homeostasis of the plants.
Thus, the correct answer is option (2).
There is no net water movement, so there is no change in the size of the cell becauase in an isotonic environment, the relative concentrations of water and solute are equal on both sides of the membrane.
