Asexual reproduction is reproduction with only one parent. Single cell organisms Some simple animals Many plants

Asexual reproduction takes place only by mitosis A. Each offspring has the exact same DNA as the parent. B. There is NO variation, or change. C. This type of reproduction is rapid and usually results in large numbers of offspring being produced

Binary Fission Spore Formation TYPE WHAT DOES IT? WHAT IS IT? Budding Regeneration   Bacteria Protozoa Algae Parent divides into two equal parts Just like mitosis Binary Fission Parent divides into two unequal parts Parent develops small growths, called buds Parent and offspring are not the same size Yeast Hydra Sponges Specialized cells that are released and grow into adult organisms Usually large numbers are produced Fungi Algae Protozoa Sea Star Sponges Planarian Earthworms Ability to regrow lost body parts

Human Asexual Reproduction If humans could reproduce by asexual reproduction, it might look like this…….any questions?

Spores

Regeneration Sea Star regenerating from one arm Planarian regenerating a new head after being cut
