- 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.

A single leaf cell may be designed to simply photosynthesize, or create sugars from the energy in light.
Jul 31, 2019 · Epidermal cells secrete a waxy substance known as the cuticle that aids in protection and keeps water from evaporating. Its epidermis gives the leaf structure, support and protection. The specialized stomata cells function as gate keepers, allowing carbon dioxide to enter and oxygen to escape.
Mar 22, 2022 · The xylem is responsible for transporting water and nutrients from the soil to the leaves. The phloem transports sugars from the leaves to all other cells of the plant. The spongy mesophyll layer is just below the palisade mesophyll layer. Its cells are irregularly-shaped and loosely packed.
Oct 31, 2023 · The xylem consists of tracheids and vessels, which transport water and minerals to the leaves. The phloem transports the photosynthetic products from the leaf to the other parts of the plant. A single vascular bundle, no matter how large or small, always contains both xylem and phloem tissues.
Leaves, and the structures they contain, play key roles in photosynthesis. When it comes to photosynthesis, the most important parts of the plant are the leaves. Their cells and structures are specialized to take in light and allow for gas exchange with the air around them.
The main function of a leaf is to produce food for the plant by photosynthesis. 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.
Leaves come in many shapes and sizes. This video walks through the major internal cell types, including the waxy cuticle, upper epidermis, palisade mesophyll...
