Study Notes
Bacterial Cell Structure
- The plasma membrane is responsible for regulating the transport of nutrients into the bacterial cell and the removal of wastes out of the cell.
- It acts as a selective barrier, controlling the movement of ions and molecules.
Basic Shapes of Bacteria
- Bacteria exhibit three major basic shapes:
- Cocci: Spherical-shaped bacteria.
- Bacilli: Rod-shaped bacteria.
- Spirilla: Spiral or corkscrew-shaped bacteria.
Pili Functionality
-
Pili are hair-like structures on the surface of bacteria that serve critical functions, including:
- Attachment to surfaces and other cells, facilitating colonization.
- Transfer of genetic material between bacterial cells through conjugation.
- Enhancing motility in some species.
Algae Classification
- Algae are classified under the group of microorganisms known as protists.
- They are primarily aquatic and act as photosynthetic organisms, converting sunlight into energy.
Bacterial Reproduction
- Most bacteria multiply through a process called binary fission.
- This asexual reproduction involves the cell division of a single bacterial cell into two identical daughter cells.
