Asexual Reproduction
• Involves the process of
• Offspring are genetically to parent
mitosis

Binary Fission
• Parent divides into halves after nucleus replicates
• No parent remains daughter cells grow to normal size
• Occurs in , , and

Budding
• Parent organism divides into halves
• Daughter cell forms from outgrowth or off parent
• Buds may or remain attached and form a

Regeneration
• Ability to back missing parts• The more the organism, the
it is to regenerate• Occurs in simple organisms such as

Vegetative Propagation
• of a body of a multicellular organism gives rise to a organism
• Common in - using stems, leaves, or roots
• Can occur or

plants
naturally artificially

Natural Vegetative Propagation• Bulb-
• Corm-
• Tuber-
• Runner-
• Rhizome-
Short underground stem with stored food & fleshy leaves Ex. Onion, tulipShort underground stem with stored food Ex. Water chestnutEnlarged underground stem Ex. potato
(stolon) horizontal stem with buds along ground’s surface Ex. strawberry
Underground horizontal stem
Ex. ginger

Artificial Vegetative Propagation
• 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. )
