AP BIOLOGY

Detailed explanation-1: -Because the cuticle is made of wax, it is very hydrophobic or ‘water-repelling’; therefore, water does not move through it very easily. The thicker the cuticle layer on a leaf surface, the slower the transpiration rate.

Detailed explanation-2: -Transpiration is just a subset of the evaporation process, and it’s the water that is inside plants, and then when that evaporates and moves into the atmosphere, that process is called transpiration.

Detailed explanation-3: -What is evaporation and transpiration in the water cycle? Evaporation is the process of surface water absorbing heat energy from the sun or from warm air and changing from a liquid to a gas. Transpiration is when water evaporates through plants.

Detailed explanation-4: -Temperature – As temperature increases, the rate of evapotranspiration increases. Evaporation increases because there is a higher amount of energy available to convert the liquid water to water vapor. Transpiration increases because at warmer temperatures plants open up their stomata and release more water vapor.
