How do plants maintain homeostasis? Select all that apply. 1. By exchanging gas through stomata. 2. By closing stomata to prevent water loss. 3. By exchanging gas through stigmas. 4. By growing towards sunlight. 5. By altering the activity within a cell with chemical transmitters.

Option-1, 2 and 4 are correct.

Explanation:

Homeostasis is defined as the regulating and maintaining the internal conditions of the organisms at the tissue and cellular level irrespective of the outer environment.

Like animals, plants also maintain the homeostatic conditions by:

1. The leaf epidermis which possesses stomata allows the exchange of gases by opening stomata only to exchange gases but not to allow the loss of water through the process of transpiration.

2. They show phototropism and the hormones control the movement of plat towards a light to have access to sunlight and maintain the internal temperature.

Thus, Option-1, 2 and 4 are correct.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
