2. ____________ organisms cannot make their own food. These organisms may live off of dead
and decaying matter. They are called _____________. If an organism lives off of a living host
they are called ____________. If an organism can make its own food it is called a(n)
____________.

3. Since bacteria are single-celled organisms it is very hard to study them without a good

5. When a bacterial cell reproduces asexually it is called ____________. During this process it
___________ as the cell prepares to divide. This is different from what occurs to a cell during
mitosis. Each daughter cell is __________ the size pf the original cell.

6. The sexual form of a bacterial reproduction is called ____________. During this process the
two bacterial cells ____________ during the first step of the process. A special cytoplasmic
tunnel, called the _________ is produced connecting both cells. This connection allows one of the
cells to ____________ to the other cell. Some bacteria have small circles of DNA called
_____________.

7. ______________, ____________, ______________, and _______________ are examples of
