BACTERIA
Main Characteristics
Have a cell wall
Prokaryotic cells (no nucleus)
Can live in many environments (soil, water, inside organisms)
Microscopic, single-celled organisms
Some are helpful while others can cause disease
Bacteria facts in Real-world applications
Used in making food (yogurt, cheese)
Help digestion in humans
Used in medicine (antibiotics production)
Help clean the environment (bioremediation)
Some cause diseases (e.g., infections)
Bacterial Reproduction Methods
Very fast reproduction under good conditions
Can exchange genetic material (conjugation)
Binary fission (main method, one cell divides into two)
Bacterial Classification Systems
By cell wall (Gram stain)
Gram-positive
Gram-negative
By oxygen use
Aerobic (need oxygen)
Anaerobic (do not need oxygen)
By shape
Bacilli (rod-shaped)
Spirilla (spiral-shaped)
Cocci (round)
