The myriad solutions to the reproduction puzzle fall neatly into two divisions-sexual and asexual. Both have their advantages and disadvantages. This five-slide set will help to illuminate the basic differences and provide visual examples for each. Asexual reproduction is shown by fission of Paramecium and by budding in Hydra. The complex structures often associated with sexual reproduction are illustrated by a cross section of a Ranunculus flower, and by separate cross sections of a mammalian testis and an ovary.
