1The stamen is the female part of the flower, and the pistil is the male part. Yes No Do you agree with the statement?

2Pollination can occur in a single plant or between two plants. Yes No Do you agree with the statement?

3Food is stored in seeds. Yes No Do you agree with the statement?

4Seeds and spores both have multicellular embryos. Yes No Do you agree with the statement?

Parts of a Flower Plants reproduce with flowers and some can reproduce without flowers. Stamen is the male part of the plan, and pistil is the female part of the plant. Pollen is a grainy yellow powder made at the top of each stamen. First paragraph pg. 102

Passing Information Pollination Plants pass information through the DNA which contains information for making all parts of the plant. Pollination is moving pollen from the stamen to the pistil, which can be done by wind, water or animals (insects, bats and birds). A tube grows from the pollen down to the egg cells in the bottom of the pistil. S perm cells travel down the tube and join the egg cells. This joining of cells is called fertilization and the egg grows and changes into a seed with a tiny plant inside. New plants look their parents because it gets half the DNA comes from the male parent and half from the female parent. This is sexual reproduction and it comes from two parents. First paragraph pg. 104

Going to Seed Spreading Seeds Reproducing without Seeds The three parts of the seed is seed coat, embryo and endosperm. The embryo has new plant inside and is protected by the seed coat. Monocot seeds have one cotyledon (area of stored food), dicot seeds have two cotyledon. Some seeds fall to the ground and grow near the parent, while other seeds are spread to different places by animals. The embryo will stay in the seed until the temperature and moisture are right. Asexual reproduction is when there is only one parent and the offspring gets all the genes from one parent, the DNA is the same as the parent. A spore is a single plant cell that can grow into a new plant and is different that a seed because spores are not made by fertilization.
