Study Notes
Bacteria Kingdom
- Bacteria belong to the Monera kingdom, which includes single-celled organisms.
Cell Structure
- A group of bacteria, known as Mycoplasma, lacks a cell wall and has a cell membrane made up of different lipids.
- The characteristic feature of Eubacteria is the presence of a peptidoglycan cell wall.
Extreme Bacteria
- Extremophiles are bacteria that live in extreme and harsh conditions.
- Halophiles are a type of extremophile that thrive in extremely salty environments.
- Thermophiles are a type of extremophile that thrive in extremely high temperatures.
- Methanogens are a type of extremophile that thrive in extremely anaerobic environments and produce methane as a byproduct.
Bacterial Shapes
- Cocci are spherical-shaped bacteria.
- Bacilli are rod-shaped bacteria.
- Spirilla are spiral-shaped bacteria.
Nutrition and Metabolism
- Cyanobacteria prepare their own food by the process of photosynthesis.
- Chemosynthetic autotrophs are bacteria that synthesize their own food using energy from chemicals.
- Heterotrophic bacteria are dependent on other organisms for their nutrition.
- Parasitic bacteria depend on the host for nutrition and cause harm to the host.
Identification and Staining
- Gram's staining is used to identify bacteria by distinguishing between Gram-positive and Gram-negative bacteria.
- Gram-positive bacteria have cell walls that appear violet under the microscope after Gram's staining.
- Gram-negative bacteria have cell walls that appear pink under the microscope after Gram's staining.
Reproduction and Genetic Transfer
- Bacteria mainly reproduce asexually through binary fission.
- The process of transformation involves the transfer of DNA from one bacterium to another.
