Key points. The leaf is one of the most important organs of a plant. Leaves produce food for the plant through a process called photosynthesis. The leaves of different plants vary widely in...
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.
So, plant cells are living building blocks of plants, and they carry out the common processes of living organisms. You can see here's a picture of a plant cell just to help you, because for this task, you're going to need that picture. What we'd like you to do is explain why the plant cell is described as living.
In this STEM and Beyond video we will learn all about the different parts of a leaf and what each part does.

Mar 22, 2022 · Learn about the structure and function of the cells in leaves. Leaves are essential to life on earth. They can be tiny, like the leaves of the common water fern (Azolla filiculoides), which are just one millimetre in length. And they can be large, like the leaves of the raffia palm (Raphia regalis) that can grow to be 25 metres in length.

Plant leaves are made up of cells that contain structures called chloroplasts. Photosynthesis takes place in chloroplasts. Chloroplasts contain chlorophyll, which absorbs light for photosynthesis. Plant leaves are thin to allow light to pass through to cells containing chloroplasts.
