Vascular bundles are collateral and closed. They regulate the process of transpiration and gaseous exchange. Lab Apparatus List. Diagram of Stomata. Diagram showing plant cell with stomata and guard cell. Stomata: Stomata (sing.-stoma) are very minute openings found in the epidermal layer of leaves, stem and other aerial parts of the plant. Most stomata are on the lower epidermis of the leaves on plants (bottom of the leaf). For a typical leaf, we use that of the umbrella tree, which is commonly sold as a foliage plant throughout North America and Europe. In botany, a stoma (plural "stomata"), also called a stomate (plural "stomates") is a pore, found in the epidermis of leaves, stems, and other organs, that controls the rate of gas exchange. They can either be present on either the sides or just on one side of the leaf. Subsidiary Cell: These cells are located adjacent to the guard cell in the stoma of a leaf.
