


Some organisms reproduce asexually
During asexual reproduction all
genetic information comes from a single a single parent
Organisms that result from asexual
reproduction are genetically identical to the parent
Fission

Single celled organisms reproduce
by splitting into two.

This is often the only mode of
reproduction for these organisms.

Examples would be paramecium and
bacteria.
Fragmentation

Some animals can grow from a
separate piece of parent animal.

This only happens in the simplest of
animals.

These animals may also reproduce
sexually.

Example: Flat Worm
Budding


Cell division produces a bud.
As a bud grows it forms an identical
copy of its parent, then separates from its parent and becomes independent.

These organisms may also be able to
reproduce sexually.

Example: Hydra
Vegetative Propagation





New plants can be reproduced by
selection of parent plants that have been cut off.
Cambium cells from stems, roots,
and leaves of a parent plant can take root and sprout.
New plants reproduced in this way
are genetically identical to the parent plant.
These plants can also reproduce
sexually.
Example: Spider plants and willow
trees.
Parthenogenesis



Some animals may produce eggs
that develop directly into offspring without fertilization.
Often, these organisms may
reproduce sexually.
Examples: Insects, reptiles, and
fishes.
The choice between sexual and asexual reproduction is typically determined by environmental
conditions.
