Leaf Structure DRAFT. All leaves have the same basic structure - a midrib, an edge, veins and a petiole. You need to understand the structure of the tissues in a leaf together with their functions. Mesophyll tissue is differentiated into palisade and spongy parenchyma in dicot leaves while the mesophyll is undifferentiated and contain only spongy parenchyma in monocot leaves. Leaf structure Marthese Azzopardi. Complete the table below: Write the raw materials and products of . Mesophyll of isobilateral leaves is not differentiated into palisade and spongy tissues. The internal structure of each leaf consists of several layers; externally, top and bottom, a wax cuticle on the outside of a thin, transparent epidermis layer protects the leaf whilst allowing light through. B. Anatomy of dicot & monocot leaf Apurva Pednekar. The main function of a leaf is to produce food for the plant by photosynthesis. Leaf Structure, Function, and Adaptation. How can you distinguish a monocot leaf from dicot leaf in their internal structure. The assessment will ask about the stomata and photosynthesis. Learning Objectives. Here is how: Wide surface area Most green plants have leaves that are broad, flat, and exposed to capture as much of the sun’s energy (sunlight) needed for photosynthesis. The outer layers of the leaf are designed to protect it, serving as a strong barrier. Dicotyledons: 1. c) Palisade Mesophyll: Tightly packed upper layer of chloroplast containing cells. Food energy. Protection. Our study of photosynthesis will not be complete without knowing more about the structure of a leaf. An outline of the internal structure of the stems is given here. photosynthesis. Describe the internal structure and function of a leaf. The thickness or cuticle on the both surface is equal. This structure is independent of the semantics of the objects. Internal structure of a leaf . Class 6: Science: Leaf and Flower in a Plant: Structure of a Leaf Internal structure of the leaf. These can be placed together to show how cells make up larger structures. In view of the fact that wide diversities exist as regards the nature of the plants, a few common dicotyledons and monocotyledons have been selected for the study of anatomical structures. Play. Can easily be adapted be suitable for either KS3 or KS4. Q2: Roots take in water and minerals from the ground. Do not cut out the inside spaces of each layer.
