     • The 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. All the raw materials together help plants to perform photosynthesis.

   What is a leaf cell?

   • A leaf cell, by definition, is any cell found within a leaf. However, there are many different kinds of leaf cell, and each plays an integral role in the overall function of the leaf and the plant itself. A single leaf cell may be designed to simply photosynthesize, or create sugars from the energy in light.

   How does a leaf cell work?

   • A single leaf cell may be designed to simply photosynthesize, or create sugars from the energy in light. Other cells are designed to carry these sugars to the phloem, a specialized tube for transporting the sugars to the rest of the plant. Still other cells are specialized to carry water, which eventually form a rigid tube, the xylem.

   What does a plant cell do?

   • Allows gases and water to diffuse freely into and out of the cell. Controls the transport of other molecules. Contains enzymes for the reactions in aerobic respiration (in animals, plants and yeast). Where amino acids are joined together to make a protein. Plant cells also have additional structures:

   What structures do plant cells have?

   • Plant cells also have additional structures: Organelles that contains the green pigment, chlorophyll, which absorbs light energy for photosynthesis. Contains the enzymes needed for photosynthesis. Made from cellulose fibres and strengthens the cell and supports the plant. Filled with cell sap to help keep the cell turgid.

   Why do leaf cells form a protective layer over a leaf?

   • They form a protective layer over the leaf. They often produce waxy substances which protect the leaf from drying out or being attacked by insects. A leaf cell in the epidermis often lacks chloroplasts, the organelles responsible for creating sugar. The upper and lower epidermis vary slightly.

   Oct 31, 2023 · Leaf Structure and Function. The outermost layer of the leaf is the epidermis. It consists of the upper and lower epidermis, which are present on either side of the leaf. Botanists call the upper side the adaxial surface (or adaxis) and the lower side the abaxial surface (or abaxis). The epidermis aids in the regulation of gas exchange.
