Adaptations of Aquatic and Tertiary Organism. Within plants water is transported up the stem via the process of transpiration. The stomata, as well as permitting entry of carbon dioxide, allow evaporation of water from the plant this is the process of transpiration. Transpiration occurs all over the plant through stomata in the stem and epidermis as well as in the leaves, however the adaptation of the leaf is its large surface are this means the main source of water loss is from the leaves. There is also "cuticular transpiration" which is water loss through the cuticles of the epidermis cells, these accounts for around 5% of water loss within the plant. The rate of transpiration is specific to the environment. Experiments with the potometer and an atmometer the rate of transpiration is dependent on a wide variety of internal and external factors. The opening between the stoma creates a chamber underneath...
