Plant Anatomy Lesson for Kids

Instructor: Kathryn Miedema Dominguez

Kathryn has taught elementary students for over ten years and has her master's degree in elementary education.

Plant anatomy is the study of plant parts and how they work. In this lesson, you'll learn about the six main parts of a plant and their main purposes.

What Are the Main Parts of a Plant?

Do you know the main parts of your body and how they work? You have legs for standing and walking. Your arms connect your hands to your body and are used for holding things. Your head contains your brain that controls everything. Just like your body has important parts, so do plants. This is called plant anatomy, which means the study of the parts of living things and how they work. The main parts of a plant are the roots, stems, leaves, flowers, fruit, and seeds.


Roots are like a plant's feet that keep them stable on the ground. A seed will grow thread-like arms that dig down into the ground. The roots have many important jobs. The roots absorb water and nutrients from the soil and send it up to the plant to grow. They also hold the plant in place so that the stem and leaves can grow without falling over. Lastly, the roots store nutrients for later use such as during the winter.

Plant roots dig into the ground to absorb water and nutrients.

Most plants have a main stem that grows up from the seed towards the sun. The main stem is also an important part that keeps the plant stable. Smaller stems and leaves grow from the stem to form the rest of the plant. Water and nutrients flow through the stem to the rest of the plant.


The leaves get energy from the sun to stay alive! If a plant does not have leaves, then it will die. Leaves absorb sunlight and carbon dioxide which it turns into sugar energy to keep growing. This process is called photosynthesis.


Flowers are not just for beauty! They are an essential part of a plant because they make new seeds so that more plants can grow. The flower has to be pollinated and then a fruit will grow which contains its seeds. However, not all plants have flowers, but can reproduce in other ways.
