1. Bacteria are classified as ______________ (type of cell) and are ______________ (number of cells).

2. Bacteria are classified into ______ different kingdoms, which are:

3. The _____________ kingdom contains bacteria that live in unusually harsh environments. This group is divided into three types
1. __________________________ (live in oxygen-free environments)
2. __________________________ (live in very hot environments)
3. __________________________ (live in very salty environments)

That’s all we’ll mention about that Kingdom for now. Next we’ll be moving on to more well-known bacteria……

4. The rest of the world’s bacteria belong to the Kingdom _______________. These bacteria are the more common than those belonging to the other Kingdom.

Methods of Obtaining Food

5. Most bacteria are _____________, meaning they use organic molecules as their food source.

6. Some bacteria make their own food, like plants, these bacteria are called _____________.

7. The last group of bacteria is called Chemosynthetic or Chemoautotroph. These bacteria get their food from ______________ compounds.

Shape and Structure

8. Bacteria are usually one of three shapes: (name the shapes and draw a picture of each shape.)

11. Just like a human, a bacterial cell may have appendages. Typically, there are two types of appendages. (Name each and draw a picture of each)

1. _______________________ (hair-like structures allow for attachment to bacterial cells)

2. _______________________ (whip-like structure just for movement)

List two more that you come up with on your own:

__________________________________________________________________________________________________________________________________________

Reproduction

12. Bacteria reproduce asexually by _______________________, the bacterium copies its chromosomes, then both copies are attached to the plasma membrane, the cell then grows larger and the two copies separate to opposite sides of the cell as the cell splits.

Another way bacteria reproduce is by _____________________, a form of sexual reproduction.

Bacteria Uses

13. While some bacteria may be harmful to person’s health, bacteria do have some very beneficial uses. Name three uses for bacteria that you found and briefly explain each.

1. _______________
