Study Notes
Cell Division in Bacteria
- There are two types of cell division in bacteria: binary fission and multiple fission.
Bacterial Reproduction
- Bacteria use binary fission to reproduce, which involves the division of a single cell into two identical daughter cells.
Blue-Green Algae
- Blue-green algae, also known as cyanobacteria, are capable of photosynthesis and nitrogen fixation.
- Blue-green algae can be found in aquatic environments, including freshwater and saltwater lakes, rivers, and ponds.
- Blue-green algae are also found in soil and on rocks in tropical and subtropical regions.
Binary Fission
- Binary fission is a process of cell division where a single cell divides into two identical daughter cells.
- Bacteria can divide through binary fission every 20-30 minutes under optimal conditions.
Conditions for Rapid Cell Division
- Bacteria can divide rapidly under optimal conditions, including:
- Adequate nutrient supply
- Suitable temperature
- pH levels close to neutral
- Presence of oxygen (for aerobic bacteria)
Binary Fission vs Multiple Fission
- Binary fission involves the division of a single cell into two identical daughter cells.
- Multiple fission involves the simultaneous division of a single cell into multiple daughter cells.
Characteristics of Blue-Green Algae
- The main characteristic of blue-green algae is their ability to perform oxygenic photosynthesis, similar to green plants.
