10. When a certain plant is without water for an extended period of time, Guard cells close openings in the leaves of the plant. This activity conserves

water and illustrates

A) maintenance of a dynamic equilibrium through detection and response to stimuli.

B) a response to one biotic factor in the environment

C) cellular communication involving the action of nerve cells and receptor sites

D) an increase in rate of growth due to a low concentration of water

The correct option is (A)

Explanation:

Two profoundly particular cells, the guard cells that encompass the stomatal pore, can coordinate natural and endogenous signals so as to control the stomatal gap and consequently the gas exchange.The take-up of is related with lost water by leaves. Control of the size of the stomatal opening upgrades the productivity of water use through powerful changes in the turgor of the guard cells. The opening and shutting of stomata is controlled by the reconciliation of environmental signals and endogenous hormonal stimuli.

The answer is c : ) hope this answered your question!

idk but if i had to take an educated guess i’d say a c d
