Definition
Stoma. Stomata are small pores on the epidermis of plant leaves. The aperture of the pore is controlled by the conformation of the two guard cells surrounding the pore. When the guard cells are relatively flaccid, the stomatal pore is nearly closed, and when they are turgid, it is open.
Stomatal conductance. Stomatal conductance expresses the aptitude of stomatal aperture to control gas exchanges from or into the leaf.
Photosynthesis. Photosynthesis is a plant process that converts atmospheric carbon dioxide into more complex organic compounds, especially sugars, using energy from sunlight.
Transpiration. Transpiration is water taken up from the soil and lost through the stomata in the leaves. This loss of water as vapor through stomata is directly related to the degree of stomatal opening, the supply of water to the leaves, and the evaporative demand of the atmosphere surrounding the leaf.
