• Fruita structure that holds seeds.
• Life Cycleall of the stages in an organism’s life.
• Pollena powder made by the male part of a flower or male cone.
• Pollinationthe process that takes place when pollen moves from the male part of a flower to the female part of a flower.
• Seeda structure that can grow into a new plant.

Did you know that when you eat corn, peas, or nuts, you are eating seeds? Seeds come in all shapes and sizes, but all have the same function. covering
Parts of a Seed
A seed is a structure that can grow into a new plant. It holds a young plant that is ready to grow. This young plant is called an embryo .
stored food
A seed has parts that help an embryo survive. It holds stored food that the embryo uses to grow.
It has a tough covering that protects the embryo.

When a seed is planted in the soil, it can germinate , or begin to grow.
A seed needs water, nutrients, and the right temperature to germinate. When a seed begins to germinate, it soaks up water. That makes it swell up and break through its covering. The embryo grows out of the seed. It grows into a small plant called a seedling . A seedling can grow into an adult plant. http://www.youtube.com/watch?v=3nRVZPJdXOo

Attract pollinators and make seeds that will someday grow into new plants
Supports the plant and carries water and nutrients up and down to all parts of the plant
Food factories! They catch energy from sunlight and use it to turn the air and water into food
Are hidden underground but are very important to the plant. Roots hold the plant steady in the ground, soak up water and nutrients from the soil and even store food for the future.

A flower is a plant structure that makes seeds. Pants that use flowers to make seeds are called flowering plants .
Flowers make seeds. Flowers have pollen and eggs. When pollen and an egg come together, a seed can form.
Wind may blow pollen from one flower to another. Bees can carry pollen too.
They drink a sweet liquid called nectar , from the flower. Sticky pollen clings to their bodies. Then they carry it to different flowers.
