approximately the same number of stomata are found on upper surface (adaxial) and lower (abaxial) surface. There are several ways by which plants in dry conditions tend to reduce transpiration, loss of water to the atmosphere. The structure of a hydrophytic leaf differs from a mesophytic leaf due to selective pressures in the environment -- water is plentiful, so the plant is more concerned with staying afloat and preventing herbivory. Boundary layers increase as leaf size increases, reducing rates of transpiration as well. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. It will satisfy your longings for a comforting, decadent dessert treat.How long does a Kangvape ONEE stick last?How long does a onee stick Kangvape last? How do mangroves prevent coastal erosion?

We have recently shown that sugars, as the end product of photosynthesis, close the stomata of various angiosperm species, to coordinate sugar production with water loss. Transpiration is the process by which water is evaporated from the leaves of plants. These pores are called stomata and allow carbon dioxide (\(\ce{CO2}\)) to enter the leaf for photosynthesis. This helps in protecting against the escaping water vapor from air currents thereby decreasing water loss from the leaf and hence decreasing transpiration.
