The process of transferring pollen from the anther of a flower to the stigma is called pollination.

Bee In Flightby respres on Flickr

Bees can help flowers make seeds. Bees usually look for pollen and sweet juice. Every flower has pollen, although some flowers don't have sweet juice. The bee's first job is to move pollen from the anther of one flower to the female stigma of another flower.

An anther is the male part of a flower that has pollen grains on it. A stigma is the female part of a flower that receives the pollen. In other words, when a bee gets pollen from a flower, the pollen sticks to the bee.

The bee goes to another flower and the pollen falls onto the stigma. Most flowers
 use this pollen to make seeds. Other
 flowers use their own pollen to make seeds.

Each tiny pollen grain grows into a long tube. These are called pollen tubesThey grow until they come to the ovule

The ovule is the section of a flower where the pollen tubes meet. Now a male gamete from the pollen tube joins the egg from the ovule and a seed is born.

A seed has everything it needs to produce new plants. No seed can grow with the fruit around it. A seed has to have enough water,
 good soil, and sunlight.

Sometimes people plant them and other times the seeds get planted on their own. People also put seeds in gardens or fields, and water and fertilize the seeds.

Some seeds travel by sailing in the wind. Others float in the water to get to the land. Others hitchhike on animals. Some just get blown in the wind. Seeds can also grow in a flower and drop to the ground.

When the seed leaves the flower or whatever it was in, it's called dissemination. This is one of the most important steps in the seed's
 life. Some tree seeds drop directly below the parent and die because there is not enough light or food for them to grow.

The seeds that travel by wind must be light-weight. Some of these seeds have wings, like the maple seed. Some of these seeds have gone 32 miles on a windy day.

Another flying seed is the dandelion which gets planted because ants carry the seeds down into their hole.

The hitchhikers are built with spikes. They get stuck to animals and eventually fall off. Some seeds have a sticky substance that makes them stick to animals. Then they travel to another place to grow.

All plants produce flowers for the same reason: to make seeds so another plant can grow.

Coral vine and honey beesby sylvar on Flickr

A flower is the part of the plant that makes the seeds. The main parts of a flower are the carpels and stamens. These parts are often found in the center of the flower.

There are egg cells in the carpel and pollen cells in the stamen. All flowers have four basic parts: sepals, petals, carpels and stamen. Different flowers have different
 numbers and shapes of these parts.

Flower markings are like the landing lights on an airport runway. They guide the bee into the flower's pollen grains.
