Answer:
maintain homeostasis
Step-by-step explanation:
Plants maintain homeostasis in two ways:
1. By keeping their stomata open to allow the diffusion of gases so that photosynthesis reaction takes place in the organisms.
2. By maintaining the water content in plants by evaporating the excess amount of water through leaf stomata. The loss of water is own of the cause of the transpirational pull in the plants.
Thus, plants maintain their homeostasis by these two mechanisms.
