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