What is a Seed?
A seed is a tiny plant that is protected by a hard outer shell. Inside the shell is a tiny embryo, which is the new plant. The embryo is surrounded by a food source, which helps it to grow.
Seeds come in all shapes and sizes. Some seeds are so small that you can barely see them, while others are as big as your hand. Seeds can be round, oval, or even shaped like stars.
Where Do Seeds Come From?
Most seeds come from flowers. When a flower is pollinated, it produces a seed. The seed is then dispersed by the wind, animals, or water.
Some seeds come from fruits. When you eat a fruit, you are also eating the seeds. The seeds pass through your digestive system and are then deposited in the ground.
