- The tissue in plants that transports the products of photosynthesis, including sugars and amino acids. These specialised tissues move substances in and around the plant. Functions of leaves The function of a leaf is photosynthesis - to absorb light and carbon dioxide to produce glucose (food).

An epidermal leaf cell is any cell which protects the outside of the leaf. These cells are often short and flattened, much like a square pancake. 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, t...
The palisade mesophyll consists of a type of leaf cell specifically designed to carry out photosynthesis. These cells are absolutely packed with chlorophyll, and simply work their hardest to pump out as much sugar as they can. This sugar they release into the intracellular space, where it works its way to the next type of leaf cell.
Spongy mesophyll is exactly what it sounds like: a loose matrix of structural mesophyll cells. These cells are not neatly packed into rows like the palisade cells. Rather, they form networks around bundles of vascular cells, and transport materials to and from the bundles. Like palisade mesophyll leaf cells, they can photosynthesize, but they carry...
The last type of leaf cell is not specific to the leaf, as it travels the entire length of the plant. The cells around the xylem and phloem together make the vascular bundle. These highly specialized cells allow water and minerals to flow up from the roots, while transporting the products of photosynthesis to the entire plant. Like the arteries and...

Oct 31, 2023 · Similar to the stem, the leaf contains vascular bundles composed of xylem and phloem. 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.
May 9, 2023 · Structure of the Leaf. Plant leaves have complex structures with layers of different tissues containing specially adapted cells. The table below describes the different structures in a leaf and their functions. Leaf Structures Table. Diagram showing the cross-section of a leaf.
Feb 17, 2023 · Leaves are complex organs consisting of several layers serving various essential functions. They are the site of photosynthesis in plants, producing food. For cellular functions like photosynthesis and respiration, leaves require several cells and tissues to work in coordination. Different plant cell types form three main types of tissues in ...
