-Transpiration is the evaporation of water from the surface of a plant.
-Water is heated in the leaf from the sunlight and is turned into gas. Evaporation then occurs through the stomatal pores.
-Sunlight enters the leaf through the chloroplast cells but not all of the light is absorbed by the chloroplast cells.
-Water that is carried from the xylem moves through the spongy mesophyll, and the area above the stomatal pore is where the liquid turns into gas.
-Water vapor gas diffuses through the pore of the leaves down a steep diffesion gradient.
sunlight is absorbed by the leaf structure this is then emitted as heat.
ReplyDeleteThe heat causes the phase change
Water vapour diffuses down a gradient from High conc to a low conc
