An example of how a plant maintains homeostasis is by regulating the action of guard cells. Guard cells are specialized cells found in the epidermis of leaves that control the opening and closing of stomata, tiny pores that allow for gas exchange in plants.
1. When a plant needs to conserve water, the guard cells will close the stomata to prevent excessive water loss through transpiration.
2. On the other hand, when a plant needs to take in carbon dioxide for photosynthesis, the guard cells will open the stomata to allow for gas exchange.
By regulating the opening and closing of stomata through the action of guard cells, plants can maintain homeostasis by balancing water loss and gas exchange to meet their physiological needs.
