|
Insects fly from plant to plant, collecting pollen from one plant and transferring it to another.
| ||||
|
This process is called pollination. | ||||
|
The anther contains the pollen and is held up high by the filament. These parts of a flower are the male parts and together are known as the stamen.
| ||||
|
When the pollen is transferred to a new plant it attaches to the slightly sticky stigma.
Pollen grains then travel down the tube called the style to the ovary. | ||||
|
Pollen grains then travel down the tube called the style to the ovary. The ovary contains ovules. When the pollen reaches the ovules they are fertilized and seeds start to develop. The style, stigma and ovary are the female parts of the flower and together are called the carpel (or pistil). | ||||

|
This seed is dispersed by the wind. It is shaped to spin and float away from the parent plant to find the space and light it needs to grow. | ||||
|
Dispersal by explosion. | ||||
|
These seeds have tiny hooks on them so that they can attach themselves to clothes or animal fur. These seeds are dispersed by animals. They are carried away from the parent plant and dropped elsewhere. | ||||
|
These seeds also have tiny hooks on. They are sometimes called burrs. | ||||
|
Some seeds are eaten by animals and the seeds pass through their digestive system to be expelled as waste. | ||||
|
These poppy seeds are shaken out of holes in the top of the seed pod. This is a different kind of wind dispersal.
| ||||
|
Once the conditions are right the seed can germinate, (begin to grow). | ||||
|
Seeds will germinate when the conditions are warm and damp. | ||||
|
This is the beginning of the next generation of plants. | ||||
