Producing New Plants

WORDS TO KNOW Petals- surround and protect the other

parts of the flower Stamens- The male part of a flower Pollen grain- a small part that holds the

male cells of a plant Pistil- The female part of the flower Ovary –The bottom part of the pistil Pollination –The process by which pollen

grains move from a stamen to a pistil

HOW DOES POLLEN MOVE? The colorful petals and nectar of a

flower attract insects and birds. Pollen stays on the insects because it is

sticky. As the insects and birds move from

flower to flower the pollen is transferred to other flowers, causing pollination.

Pollen MUST stick to the same kind of flower it came from.

HOW DOES A SEED FORM? 1. the pollen sticks to the pistil and

begins to form a tube. 2. The tube reaches the ovary and the

male cell of the pollen goes into the ovary.

3. inside the ovary there are ovules, as the male cells travel into the ovary, they pair with an ovule. This is called fertilization.

4. The joined cells form into a seed, as the seed develops the ovary grows thick. The ovary is a fruit, the fruit around the seeds protects them.
