1. Bacteria

2. The Bacterial Cell
Bacteria are prokaryotes. The genetic material in the cells is not contained in a nucleus.
Bacteria Structure:
Cell wall
Cell membrane
Cytoplasm
Ribosomes
Flagella

3. Bacteria have 3 basic shapes:
Rod, Spherical, Spiral

4. Binary fission is asexual reproduction.
Under favorable conditions, bacterial cells divides by fission once every 20 minutes.
Binary fission is asexual reproduction.

5. Conjugation is
sometimes
considered
sexual reproduction in bacterial cells because two cells combine their genetic material.

6. Endospore: Small, rounded, thick-walled resting cell that forms inside a bacterial cell. It contains the genetic material and some cytoplasm. Formed when environmental conditions are unfavorable for growth of bacteria so endospores are formed. They can resist freezing, heating, and drying as well as survive for many years.

7. Food Some bacteria make their own food and are called autotrophs.
Ex: Blue-Green Bacteria
and Chemosynthetic
bacteria
Others are heterotrophs and
obtain food from decaying
organisms, milk, or meat.
