Microorganisms Classification Quiz

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.
