When it comes to plants, knowing about the parts of a seed is like peeking into how they grow. Picture it like this: the outside layer, called the seed coat, is like the seed’s protective skin. Inside, the cotyledons store food that helps the seed start growing. Then there’s the embryo – it’s like the baby plant waiting to burst out with a shoot and root. The tiny radicle is the start of the root. All these parts work together to make sure the plant grows strong and healthy.

Seeds are like nature’s tiny life capsules, holding the plan for a new plant in their simple-looking shells. These little structures are special because they contain all the important stuff needed for a new plant to grow – information about how it should be and the food it needs. In this guide, we’ll take a good look at the different parts that make up a seed. Each part has a job to do, and together, they make sure a plant goes from sleeping to growing into a strong and lively presence.

What is Seed?

A seed is like a tiny, sleeping plant in a small package. It has a protective coat on the outside. Inside, there’s a baby plant and some food for it. When a seed gets the right conditions, like water and warmth, it wakes up and starts to grow into a new plant. So, a seed is like a magical capsule that holds the beginnings of a new plant.

Types of Seed

Seeds come in various types, each with unique characteristics. Here are some common types of seeds:
