Chapter 10 & 11 Sexual Reproduction and Genetics

Chapter 10 & 11 Sexual Reproduction and Genetics. I. Meiosis produces four haploid sex cells from one original diploid (2n) cell. A. Eggs are gametes produced by the female. B. Sperm are gametes produced by the male. C. Diploid cells ( 2n ) are cells with two of each kind of chromosome.

REPRODUCTION

REPRODUCTION. In asexual reproduction, one individual produces offspring that are genetically identical to itself. These offspring are produced by mitosis. There are many invertebrates, including sea stars and sea anemones for example, that produce by asexual reproduction. ASEXUAL REPRODUCTION.

Flowering Plants

Flowering Plants. By Neil Bronks. The Parts of a Flower. Most flowers have four parts: sepals, petals, stamens, carpels. The parts of a flower. Sepals protect the bud until it opens. Petals attract insects. Stamens make pollen. Carpels grow into fruits which contain the seeds.
