Seeds

What is a seed?

Picture
A seed is a small object produced by a plant from which a new plant can grow.

Where do seeds come from? What do they produce?

Seeds come from fruit. When a seed germinates, a plant grows out of it. After the plant matures, it reproduces. For flowering plants, that means they make flowers to attract pollinators. Pollen is delivered to flowers by bees, wind, or a number of other channels. Sperm cells leave the pollen and fertilize the eggs, which are found deep inside the flower. The outer parts of the flower (the parts we think are pretty) then die, but the inner parts that contain the fertilized eggs develop into fruit. All fruits contain seeds (so tomatoes and zucchinis are fruits, not vegetables). The fruit's job is usually either to provide food for the baby plant or to tempt an animal to eat the fruit, spreading the seeds in the process. Once the seeds are out of the fruit and into the ground, they grow into new plants.

Things to Know about Seeds
1. All plants start as seeds.
2.There are some seeds we can eat and some we cannot
3. Seeds can travel! They do so by water, wind, and animals!
4. Each seed contains a plant embryo within it.

How Plants Disperse their Seeds
Plants disperse their seeds in lots of different ways.

Some seeds are 
transported by the wind and are shaped to float, glide or spin through the air.

Plants growing near a river may use the flowing water to transport their seeds.

Some seed pods are designed to explode and throw the seeds a good distance from the parent plant.

Many plants also use animals to 
carry their seeds. This type of seed may have handy hooks which attach to an animal’s fur.

Alternatively, the plants might make tasty fruit to enclose the seeds, which 
attract animals to eat them.
