    Study Notes

    Cell Structure and Function

    • Cells are the basic units of structure and function in an organism.
    • The cell is the lowest level of organization that can perform all activities required for life.
    • All cells are enclosed by a membrane and use DNA as their genetic information.

    Cell Types

    • There are two basic types of cells: prokaryotic cells and eukaryotic cells.

    Similarities between Prokaryotic and Eukaryotic Cells

    • Both types of cells have DNA as their genetic material.
    • Both types of cells have ribosomes.

    Differences between Prokaryotic and Eukaryotic Cells

    • Eukaryotic cells have a nucleus, while prokaryotic cells do not.
    • Eukaryotic cells have a membrane-bound nucleus, while prokaryotic cells do not.
    • Eukaryotic cells are usually multicellular, while prokaryotic cells are usually unicellular.
    • Eukaryotic cells have organelles such as mitochondria and Golgi apparatus, while prokaryotic cells do not.
    • Eukaryotic cells have larger ribosomes, while prokaryotic cells have smaller ribosomes.
    • Eukaryotic cells have more than one chromosome, while prokaryotic cells have one, but not a true chromosome.
    • Examples of eukaryotic cells include animals and plants, while examples of prokaryotic cells include bacteria and archaea.
