Types of Reproduction
Name_________________per__date___
I. Asexual
_____________ reproduction occurs when a new organism is produced from
_______________. The genetic material of the new organism is identical to the
genetic material of the parent. So the _____________ and the ____________have
all of the __________________.
Organisms that are smaller and less complex are more likely to reproduce asexually.
__________________________________ like ____________ and
______________ reproduce asexually. Many plants and fungi can reproduce
asexually as well. A few animals can reproduce asexually.
II. Budding
Three types of asexual reproduction are budding, regeneration, and fission.
_____________ is the process when a new organism begins to form on the side of
the parent and eventually breaks off. Budding is most common in
__________________________.
III. Regeneration
_____________________ is the ability to restore lost or damaged tissues, organs,
or limbs. It is most common in animals that do not have a __________________ like
worms and starfish. Sometimes, if an organism loses a limb or if the organism is split
into two parts, both parts will regenerate the missing pieces, creating two organisms
from one.
IV. Binary Fission
____________________ occurs when a __________________ organism splits into
_______________. Bacteria and protists reproduce by binary fission.
First the parent cell makes a copy of its genetic material (the green, squiggly circle),
then the cell membrane pinches in and two new daughter cells split apart.
Because the cell copied its genetic material, the two cells have the
_______________.
V. Sexual
_____________ reproduction requires _________________. The female parent
provides an ____________, and the male parent provides a ____________. The
egg cell and the sperm cell combine to form a new individual.
The egg cell has genetic material from the female parent and the sperm cell has
genetic material from the male parent. Therefore, the offspring will have genetic
material from both parents. This is called ____________________________.
Sexual reproduction allows new individuals to have genetic variation because they
get a _________________________ from ______________________.
VI. Pollination
________________ is a form of ________________reproduction. Pollination occurs
in _______________. Pollen is taken from the male parts of one plant and delivered
to the female parts of another plant, usually by an insect. The pollen then travels
inside the flower and fertilizes an egg. The egg will grow into a seed which can
become a new plant.
Pollination also allows for genetic variation because the traits from ______________
are mixed.
