Detailed explanation-1: -Waxy leaf cuticle: It is impermeable to water and thus prevents evaporation.
Detailed explanation-2: -Increased humidity has a reduces transpiration. The lower the humidity the easier it is for the plant to release water. The type of plant is also a factor in how much a plant will transpire. For example plants grow in arid hot areas such as the desert will transpire less as they aim to conserve water.
Detailed explanation-3: -Transpiration pull or the suction force is the force which aids in drawing the water upward from roots to leaves. In leaves, some amount of water is used for photosynthesis and excess water is released into atmosphere through openings called as stomata.
Detailed explanation-4: -At high atmospheric humidity, transpiration is low. This is because the rate of transpiration is directly proportional to the saturation deficit. It is dependent on the gradient of vapor pressure. Thus, the higher the humidity, the lower the rate of transpiration.
