Botanists call the upper side the adaxial surface (or adaxis) and the lower side the abaxial surface (or abaxis). Stomata: These are small holes on the underside of the leaf that allow gases to diffuse in and out. There are five distinct parts to the structure of an average leaf. The simple sugars formed via photosynthesis are later processed into various macromolecules (e.g., cellulose) required for the formation of the plant cell wall and other structures. Palisade mesophyll absorbs light. Consider surface area. The epidermis helps in the regulation of gas exchange. This chemical gives the leaves their green colour and transfers light energy to chemical energy. h the correct definition in the right column. Leaf Blade: Wide flattened area of leaf for concentrating sunlight on photosynthetic cells. It consists of the upper and lower epidermis, which are present on either side of the leaf. Its primary purpose is to conduct photosynthesis; therefore, it is structured in a way to maximize efficiency.
