- The structure and function of a leaf are as follows:
- Photosynthesis: The main function of a leaf is to produce food for the plant through photosynthesis. Chlorophyll absorbs light energy for this process12.
- Gas Exchange: Leaves allow the exchange of gases, including intake of carbon dioxide and release of oxygen2.
- Vascular Structures: Leaves contain vascular structures that transport water from the roots into the cells2.
- Leaf Parts: A typical leaf has three main parts: petiole, leaf base, and leaf blade (lamina), each performing specific functions3.
- Epidermis: The outer layer of a leaf, called the epidermis, produces a waxy waterproof coating and contains guard cells that control water loss and carbon dioxide entry4.

Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy. The internal structure of the leaf is protected by the leaf epidermis, which is continuous with the stem epidermis.www.britannica.com/science/leaf-plant-anatomyThe structure of a leaf is specialized to trap sunlight and allow the exchange of gases such as intake of carbon dioxide and release of oxygen. They also contain vascular structures that help transport water from the roots into the cells.

The epidermis of the undersurface produces guard cells, which swell and shrink to close and open the pores (stomata) which control the loss of water vapor (transpiration) and the entry of carbon dioxide.harvardforest.fas.harvard.edu/leaves/structure 30.10: Leaves - Leaf Structure, Function, and Adaptation
