- 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.

Cell membrane ; Function: Its structure is permeable to some substances but not to others. It therefore controls the movement of substances in and out of the cell.

Plant leaves are adapted for photosynthesis and gas exchange. Roots absorb water and mineral ions through root hair cells and are transported up the plant by the xylem. Part of Biology...

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...

The table below describes the different structures in a leaf and their functions. Leaf Structures Table. Diagram showing the cross-section of a leaf.
Cell membrane: Function: Allows gases and water to diffuse freely into and out of the cell. Controls the transport of other molecules.
Oct 21, 2021 · Plant cells are the basic unit and building blocks of life in organisms of the kingdom Plantae. They are cells that have a distinct nucleus and other cellular organelles enclosed within a membrane and thus are eukaryotic in origin.
Oct 31, 2023 · The xylem transports water and minerals to the leaves; the phloem transports the photosynthetic products to the other parts of the plant. Plants in cold climates have needle-like leaves that are reduced in size; plants in hot climates have succulent leaves that help to conserve water.
