Investigation to find does light intensity affect the stomata density of leaves Aim: To find out that does light intensity affect the stomata density of leaves. Leaf stomata are the main means of gas exchange in vascular plants. Stomata are small pores, typically on the undersides of leaves, which open or close under the control of a pair of banana-shaped cells called guard cells. When open, stomata allow carbon dioxide to enter the leaf for synthesis of glucose, and also allow for water, and free oxygen, to escape. In addition to opening and closing the stomata, plants may exert control over their gas exchange rates by varying stomata density in new leaves when they are produced. The more stomata per unit area the more carbon dioxide can be taken up, and the more water can be released. Thus, higher stomata density can greatly amplify the potential for behavioural control over water loss...
