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
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.
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.
