The Structure of Plants as Relates to Transpiration

All plants need water to survive. However, plants lose huge amounts of water through transpiration, which is the evaporation of water from the aerial surfaces of a plant. In order to understand this process, one must first analyze the structure of a plant. <Tab/>Angiosperms are divided into two separate groups: monocots, with single cotyledons, or seed leaves, and dicots, with two cotyledons. Monocots usually have parallel veins in the leaf, …

…Higher temperatures result in faster rates of evaporation, and thus a greater rate of transpiration. Light causes photosynthesis to speed up. As photosynthesis produces water molecules, the rate of transpiration is reduced. Air current circulates the airy around the plant, lowering the humidity and thus the water potential of the outside air. Air current will lead to a reduced rate of transpiration. Humidity reduces the rate of transpiration because humid air has higher water potential.
