2. Reproduction
The Big Question (aka GSE)
How are sexual and asexual
reproduction the same and how are
they different?
3. Types of Reproduction
Sexual: Two parents have offspring;
offspring share traits from both
parents.
Asexual: One parent has offspring;
offspring are genetically identical to
parent.
4. Sexual Reproduction
Animals: Female parent produces an
ovum, male parent produces a sperm. Both
combine to produce an offspring, with
genetic material from each parent.
Plants: Female part of the plant produces
an ovum, male part of the plant produces
pollen. Both combine to produce an
offspring, with genetic material from each
parent.
5. Asexual Reproduction
Binary Fission: The process by which
the organism splits into two.
Most bacteria and protozoa reproduce
by binary fission.
6. Asexual Reproduction
Budding: an offspring grows out of
the body of the parent.
Hydra and sponges reproduce by
budding.
7. Vegetative Propagation
The production of a new organism
from a portion of another organism
Plants can reproduce by vegetative
propagation
8. Regeneration
The re-growth of a lost or damaged
part of an organism
Starfish can regenerate an arm
Planaria can regenerate into two
organisms
9. Reproduction
What is it?
The process by which organisms
produce offspring
What was the Big Question again?
How are sexual and asexual
reproduction the same and how are
they different?
