A stoma (singular for stomata) is surrounded by two types of specialized plant cells that differ from other plant epidermal cells. These cells are called guard cells and subsidiary cells.
The majority of stomata are located on the underside of plant leaves reducing their exposure to heat and air current.
Homeostasis is an organism ability to maintain equilibrium [which means balancing opposing forces]. When we sweat our body it is trying to stop overheating.
