Moreover, the vein structure is striated and each node contains only one leaf. 9.1.2 Outline three differences between the structures of dicotyledonous and monocotyledonous plants. The primary function of a leaf is: A. Tissue Structure of Tree Leaf. The veins consist of vascular tissues which are important for the transport of food and water.” Common Uses. Leaf Structure and Function. Viewing the leaf under the microscope shows different types of cells that serve various functions. Each guard cell contains cytoplasm, a nucleus and plenty of chloroplasts. Use the forceps to remove the leaf from the bleach and let it air dry on a clean paper plate while you work on more leaves. Students must read the sentences about the different parts of the leaf and use this information to draw the cross section of a leaf. Examine the prepared slide of a cross section through a leaf under the compound microscope. There are also the mesophyll as well as the lower epidermis. If you’ve ever eaten a piece of lettuce, cabbage, celery or onion, you’ve eaten a leaf or at least part of it. How is food synthesized by such plants.
