Notes: Sexual/Asexual Reproduction
I.
Reproduction
A. * ___Asexual reproduction_____ - a new organism is produced from one parent organism.
(growing a new plant from a piece of one)
1. -Many plants can reproduce asexually- ___vegetative propogation________________
Ex. __strawberries, potatoes, ivy____
2. An organism with no nucleus divides into two identical organisms by __binary fission___.
Example: _amoeba and bacteria__
(amoeba)
3. __Budding_____ - a small, exact copy of the adult grows from the body of the parent.
Example: __yeast, hydra_____
(yeast)
4. In __regeneration______, a whole new organism grows from each piece of the parent.
Example: __sea star, sponge, planaria___
(planaria)
1.The amoeba is preparing
for _cell division___ by
copying its DNA.
2. An amoeba prepares to divide by
expanding its _cell membrane_
Meanwhile, bundles of DNA known
as__chromosomes___ travel to
either side.
3. The amoeba has divided into two
__daughter cells__.
Each of these cells has one
complete copy of DNA. The
process of _reproduction___
is complete!!!

B. *__sexual reproduction_ - two sex cells, usually an egg and a sperm, come together.
1. *__Fertilization_____ - the joining of an egg and a sperm, generally from two different
organisms of the same species.
a. _Sperm__ are formed in the male reproductive organs. (testes)
b. _Eggs______ are formed in the female reproductive organs. (ovaries)
c. A cell that forms from fertilization is a __zygote____.
2. Following fertilization, _cell division (mitosis)_ begins and a new organism develops.
C. _Sexual___ reproduction produces offspring that are more diverse then
__Asexual_______ reproduction which produces offspring that are identical to the parent.
