Bacteria characteristics:
- Unicellular prokaryote.
- Ubiquitous.
- Used in biotechnology.
Bacteria structure:
They have-
➢ Cell envelope.
➢ Cytosol.
➢ Ribosomes.
➢ Nucleoid.
Cell – membrane characteristics:
- Has lipid Bi-layer.
- Folds into pockets called mesomeres.
Bacteria classification:
• Whether they have – gram-negative cell walls or
gram-positive cell walls.
• According to shape.
• Whether they are aerobic or anaerobic. Anerobic respiration: Absence
of oxygen.
Types of Bacteria reproductions:
1. Binary fission.
2. Budding.
3. Conjugation.
Aerobic respiration: Respiration
in the Prescence of oxygen.
