A. Organized Body Made of One or More Cells-(Jenifer A.)

The bacteria are organized by being smaller than a plant or animal cell.They are one celled organisms that occur alone in chains or groups. Another way that bacteria are organized is by having three basic shapes. The three basic shapes are coccus (sphere-shaped) ,bacillus (rod-shaped).and spirillum (spiral-shaped).

B. Obtain and Use Energy-(Jenifer A.)

The bacteria obtains and uses energy by a source of food of a way that breaks down the food to release it's energy.When the bacteria are autotrophs they make their own food.Also when the bacteria is heterotrophs they cannot make their own food. Also, bacteria don't use the sun's energy, they uses the energy of chemical substance.

C. Reproduce (Aisha H.)

(Video: Bacterial Asexual Reproduction)
Bacteria reproduces by asexual and sexual contact. Bacteria reproduce asexually by using fission. Fission is when 2 new cells from the bacteria start producing. Bacteria is one form of itself but, the cells are 2 and they produce with in each other. Bacteria sexually reproduce by using conjugation. Conjugation is when the bacteria forms a bridge between each other. Endospore is also a form of reproduction when the bacteria produces a thick wall that encloses the DNA.

D. Grow and Develop (Aisha H.)

A bacterium begins at a baby size when it first is formed. Then the bacterium's shape gets bigger to its adults size. The bacteria forms just like we do; we are formed small then we get bigger to our adult size.

E. Respond to Stimuli (Alexander M.)


Most bacteria do not, in fact, react by moving. Instead, the bacteria react to stimuli chemically. Surprisingly, bacteria can even sense a 0.1% change in mollecular concentrations. This means it could detect one drop dilluted in a pool of one thousand drops.
In addition, bacteria can undergo the process of sporulation in extreme conditions. To put it simply, the bacteria surround themselves in spores so that they can survive the harsh conditions until they get to better conditions.

F. Exchange Gases with the Environment (Alexander M.)

Aerobic bacteria break down food and obtain energy by using oxygen. This process of breaking down food is called respiration. Anaerobic bacteria, however, are adapted to survive without oxygen. Some anaerobic bacteria even live in the intestinal track of humans. Certain types of anaerobic bacteria cannot survive in areas containing oxygen.
Gases come into the bacteria through the cell membrane and they go out through the cell membrane.
