    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.
