Asexual reproduction means nonsexual. Asexual
reproduction occurs without using males and females. An organism
simply makes copies of itself through cell division.
Monerans are simple single-celled organisms.
Bacteria are monerans. Blue-green algae are monerans that can be
found in water or soil. Monerans reproduce by fission, which means
splitting. After duplicating their genetic material, they simply
split their single cell in half. Growth can occur very
quickly. Bacteria colonies have been known to double their numbers
every twenty minutes.
Molds, mildews, and mushrooms are fungi that reproduce
by forming spores. A spore is a single cell often protected by a
hard covering. Spores drop off of the parent and become new
organisms. New organisms can only begin if there is enough food and
water for them to live.
Yeasts reproduce by budding. A "bud,"
which is an enlargement, forms on one side of the cell. This bud
eventually breaks off to form a new yeast cell.
Some animals and plants can reproduce themselves
asexually by a process called regeneration. Regeneration means to
make or regenerate again. These plants and animals make new body
parts to replace the old ones. A starfish can grow a whole new arm
if one is cut off. If the lost arm still has a piece of the center
of the starfish it can even grow into a new starfish. Salamanders
can regenerate a leg if they lose one.
Plants can regenerate also. The most common way is
from a cutting or a leaf. The cutting or leaf is put into moist
material and a new plant begins. Other garden plants like roses
reproduce by a process called cloning. Cloning creates a new plant
just like the parent.
