1.
When an organism reproduces they
themselves. It means
making a

organisms to
.Some organisms reproduce
. Cows
make more cows and pigs make more pigs. This form of reproduction combines
genes from a mother and a father, making a genetically
organism.
2.
Other organisms reproduce
. In these organisms all the
genes come from a ________ parent. Asexually produced offspring are
genetically __________ to the parent.
Asexual Reproduction

2.
There are many methods of asexual reproduction. In some single-celled
organisms, _________________ is a method of asexual reproduction. This is a
process where the cell divides into
nearly equal sized
Bacteria cells reproduce through cell division. The cell makes
a copy of its
then sends the copy into a new bacteria
cell. Some bacteria cells can reproduce fast, making a new cell every 20
minutes.

Another method of asexual reproduction is
known as

plants
4.
Another method of asexual reproduction is budding. Unicellular yeast cells grow
new cells off of the
of a parent. When the cell is
developed it falls off and a new ________ cell is produced.

Some organisms produce offspring by splitting into pieces. This is called
