Investigating the relationship between the transpiration rate of a shoot and the degree of opening of the stomata of its leaves I will be investigating the relationship between the transpiration rate of a shoot and the degree of opening of the stomata of its leaves. Transpiration is the loss of water vapour from the surfaces of a plant. Solar energy turns the water in the plants into a vapour causing it to evaporate into the leaf's internal air spaces before diffusing out of the stomata into the air. The water is able to evaporate out of the leaf as the leaf has a high water potential and the surrounding has a low water potential. The water molecules pass down the concentration gradient from the spongy and palisade mesophyll cells into the leaf's internal air spaces before diffusing out into the air. For this experiment, I will need to vary a factor that...
