How do stomata allow plants to maintain homeostasis within their environment?
As we know, homeostasis is the maintain of the inside temperature within normal range of an organism. Stomata can open and close and let water vapour coming in or out. Stomata’s main function is to help to reduce water loss throught the plant, however, it has another function is to maintain inner temperature of the plant although this is not the main function. We must not get confused between these two. Now, let’s talk about the temperature function of stomata. When the enviroment is hot, the stomata open, and H2O vapour comes out of the stomata to the outside enviroment, because we know that H2O is cohesive ( it can “stick” to the container’s wall), and since the xylem which is the very small tube in the plants for transporting water is really small, this will help the water to continue to flow from the root to the leaves and come out of the stomata continuously, and as the water flow through the stem of the plants, IT COOLS THE PLANT DOWN !!!
