   This video lesson is designed for 3-6-year-old children. It demonstrates the basic structure of a leaf and its parts. This science lesson provides a practical life experience by introducing the child to the different shapes and colors of leaves.

   • The external parts of the leaf are the petiole, leaf base, lamina, leaf apex, and leaf margins.
   • The internal parts of the leaf are stomata, guard cells, epidermal cells, mesophyll cells, and vascular bundles (xylem, phloem, veins)
   • Stomata are tiny pores present on the surface of the leaves that help in exchanging gases, i.e. absorption of carbon dioxide and release of oxygen.

   It is the waxy layer of the leaf secreted by the epidermis, a thin layer of leaf present just below the cuticle. It performs the following functions: 1. Preventing excessive water loss from the leaves through transpiration 2. Controlling the exchange of gases such as dioxide and oxygen from the leaf surface Giving mechanical support and thus preven...

   It is a thin layer of cells below the cuticle. Mostly they are devoid of chloroplasts and thus do not perform photosynthesis. The upper epidermis performs the following functions: 1. Preventing excessive water loss from the leaves through transpiration 2. Allowing sunlight to pass through the spaces between the cells and thus helping to initiate ph...

   It is found just below the upper epidermis and is thus also called the upper leaf cells. They consist of columnar cells arranged vertically beside each other, much like the columns of a building. The columnar cells are tightly packed to maximize the absorption of sunlight. Sometimes it can consist of several layers of cells, particularly in environ...

   This layer is found below the palisade layer. Also called the lower leaf cells, the spongy layer consists of irregularly shaped cells consisting of the vascular tissues – xylemand phloem, forming the vascular bundles. The vascular tissues are surrounded by parenchymal pith and collenchymas. The cells contain minute pores called stomata (Singular: s...

   It is located on the bottom side of the leaves below the spongy mesophyll layer of cells. Stomata are essential structures in the lower epidermis. There may be up to one million stomata per square centimeter. Each stoma is flanked by kidney-shaped epidermal cells called guard cells. The guard cells control the opening and closing of stoma based on ...

   How does a leaf move?

   • It moves by diffusion through small holes in the underside of the leaf called stomata. Guard cells control the size of the stomata so that the leaf does not lose too much water in hot, windy or dry conditions. The lower part of the leaf is a spongy layer with loose-fitting cells.

   What is the function of leaves in a plant cell?

   • They are the site of photosynthesis in plants, producing food. For cellular functions like photosynthesis and respiration, leaves require several cells and tissues to work in coordination. Different plant cell types form three main types of tissues in leaves.

   How does a leaf absorb light?

   • Its top surface is protected from water loss, disease and weather damage by a waxy layer. The upper part of the leaf is where the light falls, and it contains a type of cell called a palisade cell. This is adapted to absorb a lot of light. It has lots of chloroplasts and is shaped like a tall box.
