Study Notes
Bacterial Structure and Function
- Fimbriae (or pili) are the appendages that help some bacteria attach to surfaces, facilitating colonization and biofilm formation.
Cell Wall Composition
- The cell wall in prokaryotic cells is composed of peptidoglycan (also known as murein), a thick, rigid layer that provides structural support and maintains the cell's shape.
Flagella Function
- The main function of flagella in motile bacteria is to enable movement and locomotion, allowing the bacteria to navigate through their environment and respond to stimuli.
Chromosome Location
- The single chromosome in prokaryotic cells is located in the cytoplasm, where it is coiled and attached to the cell membrane.
Plasmid Function
- The function of plasmids in prokaryotic cells is to provide extra genetic information that can be used to confer antibiotic resistance, degrade toxic compounds, or produce nutrients, among other functions.
