2. Examplesof AsexualReproduction:

a. Binary Fission="division in half", most common

form of reproduction in prokaryotes some single­celled eukaryotes. After replicating its genetic material, the cell divides into two nearly equal sized daughter cells.

Ex. Amoeba, Paramecium, bacteria

b. Budding= "lil' buddy" a new organism grows on original. Detaches when grown

Ex. Plants, Fungi, Yeast, Hydra, Sponges, some worms

c. Spore Formation(Sporulation)= produce andrelease spores which havegenetic material inside

Ex. Yeast, bacteria, mold,mushrooms, mosses, ferns,certain protozoa

d. Regeneration= regrowa lost part

Ex. Hydra, Planaria, starfish,earthworm, newts/geckos,(*Human Liver)
