Reproduction
Reproduction is the production of offspring, or new individuals, through a sexual or asexual process to make sure a species can continue.http://www.fredhoogervorst.com/

Sexual ReproductionRequires Two Sex Cells Egg and Sperm
Egg and sperm combine to form new organism
New organism is genetically different from the parents

Asexual Reproduction Involves only one parent producing
identical offspring with the exact same genetic material.

Planaria
Budding
A cell grows
from the body
of a parent cell
similar to the
way a bud
forms on a tree
branch. The
new cell breaks
away and lives
on its own. http://www.saburchill.com

Spore Formation
Fungi most often
reproduce by
making spores.
Lightweight spores
are surrounded by
a protective
covering and can
be easily carried
through air or
water to new
places.

Remember!
Offspring from sexual reproduction results in organisms that are genetically different from the parents.
Offspring from asexual reproduction are genetically identical to the parent.
