Used by many unicellular organisms, plants, and
Involves only mitotic cell division = each offspring
has exactly the same heredity as its parent.
Usually rapid compared to sexual reproduction.
Types of Asexual Reproduction Include:
Nucleus of parent cell replicates and the parent
cell divides in 2 Equal halves .
No parent remains The 2 daughter cells
grow to normal size individual.
Occurs in Algae, Bacteria and
Parent organism divides into 2 Unequal halves.
Daughter cell forms from outgrowth grow as
an independent individual.
The outgrowth is known as BUD.
Buds may breakoff or remain attached and
form a Colony.
Production of many spores in a special spore
producing structure ( spore case)
Spores are microscopic, specialized cells,
containing nucleus and cytoplasm.
Nucleus is close within a hard case.
Occurs in molds , ferns and mushrooms.
Ability to grow back missing parts.
More the organism is complete harder to grow
the missing parts.
Occurs in simple organisms such as --- flat worm
Development of a new plant from the
vegetative part of a plant.
Common in plants- using stems, leaves, or
Can occur naturally or artificially.
Bulb- Short underground stem with stored
food & fleshy leaves Ex. Onion, tulip
Corm- Short underground stem with stored
Ex. Water chestnut
Tuber-Enlarged underground stem
Runner-(stolon) horizontal stem with buds
along ground’s surface Ex. strawberry
Rhizome-Underground horizontal stem
Cutting- use partof plant to
reproduce (Ex.Spider plant
Layering- stem is bentover and covered with soil
will root and form
new plant (Ex.
Grafting- stem or bud of one plant is joined
(Ex. Seedless fruit tree
