  1. Chapter1Lesson 6 Producing New Plants

  2. 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

  3. 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.

  4. 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.
