Adaption of leaf Purpose; Thin: Short distance for carbon dioxide to diffuse into the leaf: Contains chlorophyll and other pigments: To absorb light from different parts of the Sun's spectrum: Network of vascular bundles (veins) To support the leaf, and to transport water and carbohydrates Stomata stomata: Tiny holes in the epidermis (skin) of a leaf - usually on the undersides of leaves. They control water loss and gas exchange by openng and closing.
Concept 4: Structure of a Leaf. Leaves are a plant's main photosynthetic organs. Leaf structure is closely associated with its photosynthetic function. Leaves must permit carbon dioxide access to the photosynthetic cells but impede water from diffusing out. The oxygen that is a waste product of photosynthesis must be allowed to escape from the leaf. Demonstrate your knowledge of leaf structure by placing the labels in their correct locations. NOTE: Answers to questions may be lost when you proceed to the next screen.
