Asexual
Reproduction
Uses
ONLY 1
source
of DNA
Offspring
are
IDENTICAL
to parents
Asexual Reproduction
 Reproduction that uses ONLY 1
source of DNA
 Offspring (babies) are genetically
IDENTICAL to the parent
 MITOSIS is a form of ASEXUAL
reproduction
Types of Asexual Reproduction
 Binary Fission
 Budding
 Spore Formation
 Regeneration
 Vegetative Propagation
Binary Fission
1. Parent Cell
3. Cytoplasm
Divides
2. Nucleus
Divides
4. Two
Daughter Cells
Are the offspring DIFFERENT from or IDENTICAL to the parent?
WHY??
Budding
 A smaller version
grows off the side of
the parent
 When fully developed
(but still SMALLER
than parent) it will
fall off and grow to
adult size
 Hydra, Yeast
Hydra Budding
1. Bud forms on side
of parent
2. Bud develops and
matures
3. When fully
developed, Bud
falls off
4. Seperate bud
grows to full size
Spore Formation
 Small packets of
DNA are released
from the parent.

This is called a SPORE
 Wherever the spore
lands, a new
offspring grows
 Molds and Fungi use
this method
Spore Formation
 Also called
Sporulation
Regeneration
 When a piece of the
parent breaks off
and grows into a
new organism
 Parent regrows lost
part
 Starfish, Lizards,
Newts
Regeneration
Sexual Reproduction in Plants
 Plants can
reproduce
SEXUALLY or
ASEXUALLY
 Plants have
reproductive parts
– when pollen and
egg combine that is
SEXUAL
reproduction (2
sources of DNA –
pollen & egg)
Vegetative Propagation
 When the NON
reproductive parts of a
plant (stems, leaves,
etc.) grow new
offspring…this is
ASEXUAL reproduction
 All the DNA is coming
from the leaf or stem
cell that is dividing
 Are the offspring INDENTICAL to or DIFFERENT
from the parent?
 WHY?
