Epidermis Base your answer to the following question on the diagram below which represents a cross section of part of a leaf. Bundle-sheath cells. Isobilateral monocot leaf. Many vascular bundles are arranged parallaly. It forms a protective covering on leaf vein, and consist of one or more cell layers, usually parenchyma. The structure of a leaf has adaptations so that it can carry out photosynthesis effectively. Thus they do not possess two epidermal layers. Vascular bundles are collateral and closed. Redrawn from Esau (1948) by Scott Snyder. These leaves are acicular in shape and are more or less rounded in cross-section. Model 2 — Cross Section of the Internal Structure of a Leaf Cuticle Upper epidermis Chloroplast palisade mesophyll Air Space Lower epidermis Vein Spongy mesophyll Cuticle Guard cell f Stoma 8. … Leaf vascular tissue is located within the mesophyll layer. Before we get into the layers and functions of the dicot leaf, let's first take a look at a diagram. Leaf (b) 1. List the la ers of the leaf starting at the upper cuticle all the way to the … 623): Cross section of a leaf showing parts of a vascular bundle . Next to this cut, make a thin, vertical slice-as thin as possible-of the leaf. A transverse section through a leaf of onion (Alliumcepa of family Liliaceae) would show the following internal structure (Fig. Different plant cell types form three main tissues found in leaves. Monocot and Dicot Leaf: Type # 2. Running through the petiole are vascular bundles, which then form the veins in the leaf. Procedure: Remove a leaf from the plant and place it flat on the table. Professional leaf cross-section slides. Absence of cambium. Which life functions are directly regulated through feedback mechanisms associated with the actions of the structures labeled X? These tissues include a mesophyll tissue layer that is sandwiched between two layers of epidermis. Cross section of 3-year-old grapevine arm. 3. Evelyn Bailey. Leaf Cross Section Showing Tissues and Cells. The differentiation of tissues into epider­mal, ground and vascular is clear. 4. The bundle-sheath cells are the photosynthetic cells arranged into a tightly packed sheath around the vein of a leaf. With the sharp knife or razor blade (and adult supervision), cut the leaf straight down the center. You can see these if you look at a transverse section (cross-section) of a leaf under a microscope. Although a leaf looks thin, its is made up of several layers of cells. ( 1948 ) by Scott Snyder covering on leaf vein, and consist of one or more cell,.
