Not only must she produce gametes‚ but her body must prepare to nurture a developing embryo for a period of approximately nine months. Ovaries‚ the female gonads‚ are the primary reproductive organs of a female‚ and like the male testes‚ ovaries serve a dual purpose: They produce the female gametes (ova) and sex hormones‚ the estrogens * and progesterone (pro-ges′tĕ-rōn).

the straight lines found on the coffee bean snails. These snails have many predators. Examples of these are ground beetles‚ snakes‚ toads‚ turtles and birds.

fertilization process with plants; one sperm cell combines with the egg cell and the other becomes the seed.
