Sexual and Asexual Reproduction Write on the Right Side

Sexual vs Asexual Reproduction Two parents each contribute a sex cell offspring Half of the offspring’s genes come from each parent Offspring are not identical to the parents Asexual Reproduction One organism produces one or more organisms that are identical to itself

Types of Asexual Reproduction Binary Fission: (occurs in prokaryotes such as bacteria) Parent splits into two Budding: tiny buds develop on an organism’s body and grow into another organism (ex: in yeasts, hydras, and sponges) Spores: produced by one parent, they are light so the wind can carry them (ex: fungi and ferns produce spores) Vegetative reproduction: new plants grow from stems, roots, or leaves (ex: potatoes)

Sexual Reproduction Fertilization: when sex cells join together to produce a cell called a zygote, which develops into a new organism

Advantages (do not have to write) Asexual Reproduction Organisms can reproduce quickly Offspring and parents are identical All offspring can produce more offspring Sexual Reproduction There is genetic variation (offspring are not identical) in the population which helps the species survive in a changing environment
