    Study Notes

    Prokaryotes vs. Eukaryotes

    • Prokaryotic and eukaryotic cells are the two main cell types
    • Both cell types share four common components: plasma membrane, cytoplasm, DNA, and ribosomes
    • Prokaryotic cells are small and simple, lacking a nucleus and membrane-bound organelles
    • Eukaryotic cells contain a nucleus and may have organelles
    • Prokaryotic cells are roughly 10 times smaller than eukaryotic cells
    • Organelles are tiny organs with specific structures for carrying out cellular functions
    • The nucleus contains the cell's genetic material in the form of DNA

    Prokaryotic Cell Components

    • Plasma membrane: outer covering separating the interior from the environment
    • Cytoplasm: jelly-like region within the cell; holds other components
    • DNA: the genetic material of the cell
    • Ribosomes: particles that synthesize proteins

    Prokaryotic Cell Structure

    • Nucleoid: the region within the cell that contains the chromosomal DNA
    • Capsule: outer covering (in some prokaryotes)
    • Cell wall: (in some eukaryotes), an extra layer of protection
    • Pili: short, hair-like appendages
    • Flagellum: long, whip-like structure for movement

    Eukaryotic Cell Components

    • Membrane-bound nucleus: central cavity where genetic material is housed
    • Membrane-bound organelles: compartments with specialized functions (e.g., mitochondria, chloroplasts)
    • Multiple linear chromosomes: multiple linear DNA strands, unlike prokaryotic cells' single circular chromosomes

    Additional Notes

    • Eukaryotes include animals, plants, fungi, and protists
    • Both prokaryotes and eukaryotes have ribosomes
    • Eukaryotic cells are much larger and more complex than prokaryotic cells, which allows them to handle more specialized functions
