More leaves increases the rate of transpiration as there is a larger area to lose water from 1 of 7 How does light effect transpiration rate? Light increases transpiration as stomata are open during times of light to enable gaseous exchange for photosynthesis 2 of 7 How does temperature effect transpiration rate? Higher temperatures increase the evaporation rate which means the transpiration rate increases 3 of 7 What is the effect of humidity on transpiration rate? When it is humid the transpiration rate decreases 4 of 7 What does the presence of a cuticle do? The presence of a waxy cuticle reduces the transpiration rate 5 of 7 How does water availability effect transpiration rate? If there is less water available in the soil then the transpiration rate decreases 6 of 7 How does stomata size, position and number effect transpiration? Leaves which have many, large stomata lose water much faster. If stomata are on a lower surface water loss is slower 7 of 7
