Asexual Reproduction
a. Binary Fission=
2. Examples
"division in half", most common
of Asexual
form of reproduction in prokaryotes
Reproduction:
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 and
release spores which have
genetic material inside
Ex. Yeast, bacteria, mold,
mushrooms, mosses, ferns,
certain protozoa
d. Regeneration= regrow
a lost part
Ex. Hydra, Planaria, starfish,
earthworm, newts/geckos,
(*Human Liver)

e. Vegetative Propagation:
­ in plants
­ Asexual plant parts (leaves, roots,
stems)
1) Natural­ bulbs, corms, rhizomes,
runners, tubers
Examples:
Onion, Garlic, Lily, Tulip,
Amaryllis
Bananas,
Saffron,
Freesia,
Gladiolus,
