Transpiration is often known as the loss of water from the stomata (stomata is on of the small pores located in the epidermis of a leaf or a stem on a plant, in which gases and water vapor pass through) of a plant. A closure of the stomata and a decrease of transpiration occur from factors such as darkness, internal water depletion, and extreme temperatures. Some factors that cause the stomata to open and increase in the transpiration would be illumination, a good and plentiful water supply, and fair temperatures. Most scientists consider transpiration as an important function of the stomata. Transpiration can be considered as an “engine” that draws water up from the roots. Some factors that affect the rate of transpiration in plants are light, temperature, humidity, wind and soil water. Light is a factor that affects transpiration because plants would often transpire a lot quicker in brighter areas than plants in darker areas.
