1. Reproduction
The process by which an
organism produces others
of its same kind. One
form of reproduction is …

2. Asexual Reproduction
A new organism
(sometimes more
than one) is
produced from one
organism.
The offspring will have
hereditary material uniform
with the hereditary material
of the parent organism. This
means they will be
genetically alike.

3. Types of
Asexual Reproduction
Parthenogenesis
Vegetative Propagation
Fragmentation or Regeneration
Fission
Budding

4. Parthenogenesis
Produce eggs that
develop into
genetically identical
versions of itself.
The population is
entirely female. The
females lay
unfertilized eggs that
develop into
genetically identical
females.
The Whiptail lizard lives
in the Sonoran Desert in
Arizona. This lizard will
lay an egg which will grow
into another lizard.

5. Vegetative Propagation
Common in household
plants; a piece is cut
with visual nodes,
placed in water to
develop roots, then
planted in soil.
Another type is seen in
the strawberry
plants; they produce
runners creating
more plants.

6. Fragmentation
Regeneration
The ability to restore lost
or damaged tissues,
organs or limbs.
It is a common feature in
invertebrates, like
flatworms and sea stars.

7. Fission
• Also called binary fission.
• Becoming two by division of
the complete organism.
• A type of cell division.
A single celled
organism; paramecium
undergoing binary
fission.
Diphtheria bacteria live in
the throat and produce
toxins. You are vaccinated
for this bacteria

8. Budding
• Process by which a new, duplicate plant or
animal begins to form at the side of the parent
and enlarges until an individual is created.
• Very common in plants.
Hydra in fresh water
Texas Prickly Pear Cactus

9. Pros
• Faster and easier;
one parent so no need
for fertilization.
• Doesn’t have to
travel, can conserve
energy, and be more
discreet.
• More reliable, less
steps to go wrong.
• No variations in the
population; offspring
look like the parent.
• Individual may not
adapt to changing
environment.
• Generally leads to
overcrowding and a
struggle to exist.
Cons

of the cell in the diagram below is correct?
Cell Division

B. Cell C has DNA that is only half identical to cell B.
C. Cells B and C have identical DNA but not the same
as cell A.
D. Cells A, B, C contain completely different DNA.
Animal Cell “A”
Animal Cell “C”
Animal Cell “B”
