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.
