ASEXUAL REPRODUCTION
Reproduction is the process by which an organism creates
another of its kind
Sexual Reproduction Asexual Reproduction
SEXUAL ASEXUALWith a partner (2
parents)
Alone (1 parent)
Sperm + Egg NO Sperm + Egg
MEIOSIS MITOSIS
Offspring are
genetically different
from parents (mix of
parents)
Offspring are
genetically identical
(clones)
Sexual Reproduction
Asexual Reproduction
Asexual Reproduction
- Fungus
- Bacteria
- Plants (leaves, stems, roots)
- Body Cells (skin, etc.)
- Yeast
There are 5 types of Asexual Reproduction:
1)Binary Fission
2)Budding
3)Spore Formation
4)Regeneration
5)Vegetative Reproduction
BINARY FISSION
- Parent Cell divides into 2 equal parts
(daughter cells)
- Parent Cell doesn’t exist any more.
EX: bacteria
BUDDING- Parent organism divides into 2
inequal parts
- Parent and offspring are not the
same size
- Offspring might stay attached or
break off
SPORE FORMATION- Spores are single-celled
- Spores are formed within a single cell
and then released.
- Spores are the leftovers of the
parent cell.
EX: fungus
REGENERATION
- The ability to re-grow lost or damaged
tissues, organs, or limbs.
EX: worms, starfish, lobsters, etc.
VEGETATIVE
- The new plant is exactly the same
as the parent plant
- Involves roots, stems and seeds.
- Important for nutrition and growth
of plants.
Vegetative Reproduction can be natural (it
happens on its own)
Vegetative Reproduction can be artificial
(humans help!)
BULBS- Short underground
stem with thick
fleshy leaves that
contain stored food
- Each bulb can
become a new plant
TUBERS
- Large underground
stem that contain
stored food
- Like the “eyes” of
potatoes.
RUNNER
- Stems grow over the
soil from the first
stem
- At points along
the runner, new
plants grow
RHizome- Long stems grow
under the soil
- New plants grow
along the stem
- EX: grass,
stinging nettle
