Transcript Quiz 6C part 1 (asexual reproduction)

ASEXUAL REPRODUCTION
a result of mitosis
ASEXUAL REPRODUCTION
reproduction that takes
place by mitotic cell
divisions
the production of a new
organism without the joining
of gametes
ASEXUAL REPRODUCTION
asexual reproduction provides
very little genetic variety.
FORMS OF ASEXUAL
REPRODUCTION
•
•
•
•
•
Fission
Fragmentation
Budding
Regeneration
Spore
Binary fission
•the division of cells into
2 approx. equal parts
•example: ameba
fragmentation
• a form of reproduction
caused by the breaking of a
colonial organism by a
physical disturbance
• Example:
Spirogyra
budding
• a type of asexual
reproduction in which
portions separate from the
parent to form a new
individual
• Examples:
yeast &
sponges
regeneration
• the ability to replace
missing structure; in some
organisms, serves as a
method of reproduction
• Examples:
planarian,
hydra &
starfish
spore
• a cell with a hard
protective covering
• Examples:
mold,
moss &
fungus
spore
•some are carried by
wind
•some have a whip-like
structure to swim
through water
•a single spore develops
into a new organism
