Figure 9.3. 2: Cross section of a hydrophytic leaf. Observe a prepared slide of a hydrophyte, such as Nymphaea, commonly called a water lily. Note the thin epidermal layer and the absence of stomata in the lower epidermis. In the spongy mesophyll, there are large pockets where air can be trapped. Part A is a leaf cross section illustration. A flat layer of rectangular cells make up the upper and lower epidermis. A cuticle layer protects the outside of both epidermal layers. A stoma in the lower epidermis allows carbon dioxide to enter and oxygen to leave.. 9.2 Introduction to Leaf Anatomy and 9.3 Leaf Anatomy from Botany Lab Manual.

Plant Leaves and Leaf Anatomy
Evelyn Bailey Leaves can be found in a variety of shapes and sizes. Most leaves are broad, flat and typically green in color. Some plants, such as conifers, have leaves that are shaped like needles or scales. Leaf shape is adapted to best suit the plant's habitat and maximize photosynthesis. palisade mesophyll tissue of the leaf. Palisade cells are column-shaped and packed with many chloroplasts . They are arranged closely together so that a lot of light energy can be absorbed. A. A cross section of a leaf shows that it is a complex organ built of several different kinds of specialized tissues. The tissues, in turn, are built of specialized cells, and the cells, of organelles. [Figure1] Epidermis covers the upper and lower surfaces of the leaf. The anatomy of the stem (internal structure) can be examined through longitudinal sections (cutting the stem lengthwise) or in cross sections (cutting a slice of the stem perpendicular to the length). All three tissue types are represented in the primary stem. The epidermis is the dermal tissue that surrounds and protects the stem.

Most of the root is composed of cortex tissue, and the endodermis, the innermost layer of the cortex, borders the stele. The outer layer of the root (external to the cortex) is the epidermis. Figure 3.2.3. 4: Eudicot root cross section. From center out, the xylem (in red) make an X, and the side tissues (green) make up the phloem.. Cross-Section: This leaf is similar to lilac in that its ground tissue consists of areas of palisade and spongy parenchyma. However, the spongy parenchyma has a huge amount of intercelluar space. This provides the leaf with buoyancy and a potential increase in the rate of gas diffusion. Parenchyma with this amount of intercelluar space is.
Cross Section Of Leaf Xylem And Phloem
Leaves are part of the shoot system of the vascular plant sporophyte and one of the three major vegetative (non-reproductive) organs types found in vascular plants (the others are stems and roots). The primary function of leaves is to carry out photosynthesis. Photosynthesis is the process by which a plant makes its food. Lab Objectives. At the conclusion of the lab, the student should be able to: List and give the major function of the three main types of plant tissues. Identify a monocot verses a eudicot plant by observing either root, stem, leaf, or flowers. Name and describe the various components and tissues within the root, both monocot and eudicot.
Leaf Cross Section Under the Microscope. Whereas the transparent thin epidermal skin of the leaf allows the student to observe the stomata and other epidermal cells, it would be important to prepare a cross section of a leaf to observe the arrange of cells inside the leaf structure. Requirements. A sharp razor; A leaf; Distilled water Examples of C 3 and C 4 leaf cross-sections. The C 3 /C 4 pair on the left (A, C) are unrelated, belonging to different major groups of flowering plants.. Leaf anatomy for selected cross.
