1
Types of Asexual Reproduction
2
Asexual Reproduction Involves the process of
Offspring are genetically to parent mitosis identical
3
Binary Fission Parent divides into halves after nucleus replicates
No parent remains daughter cells grow to normal size Occurs in , , and 2 equal 2 bacteria protozoa algae
6
Budding Parent organism divides into halves
Daughter cell forms from outgrowth or off parent Buds may or remain attached and form a 2 unequal bud break off colony
7
Occurs in and hydra yeast
10
Sporulation (spore forming)
Production of many in a special spore producing structure ( ) Spores are , specialized cells, containing and within a hard case Occurs in , , and spores spore case microscopic nucleus cytoplasm molds mushrooms ferns
13
Regeneration Ability to back missing parts
The more the organism, the it is to regenerate Occurs in simple organisms such as and grow complex harder starfish flat worm
16
Vegetative Propagation
piece of a body of a multicellular organism gives rise to a organism Common in using stems, leaves, or roots Can occur or new plants naturally artificially
17
Natural Vegetative Propagation
Bulb- Corm- Tuber- Runner- Rhizome- Short underground stem with stored food & fleshy leaves Ex. Onion, tulip Short underground stem with stored food Ex. Water chestnut Enlarged underground stem Ex. potato (stolon) horizontal stem with buds along ground’s surface Ex. strawberry Underground horizontal stem Ex. ginger

Artificial Vegetative Propagation
part Cutting- use of plant to reproduce (Ex ) Layering- stem is over and covered with will root and form plant (Ex ) Grafting- stem or bud of one plant is to another plant (Ex ) Spider plant soil bent new raspberry joined permanently Seedless fruit tree
