Study Notes

Lesson Objective

  • Distinguish features and functions of prokaryotic and eukaryotic cells.

Differences Between Prokaryotic and Eukaryotic Cells

  • Prokaryotic Cells:

    • Found in organisms classified as prokaryotes, including bacteria and archaea.
    • Typically unicellular, consisting of a single cell.
    • Lack membrane-bound organelles such as mitochondria, lysosomes, and Golgi apparatus.
    • DNA is located in the nucleoid region, consisting of a single strand in bacterial cells.
    • May possess a capsule for extra protection and structures like pili for attachment and flagella for movement.
  • Eukaryotic Cells:

    • Characteristic of complex organisms, including animals, plants, fungi, and protists (like algae and amoeba).
    • Can be multicellular (comprising multiple cells) or unicellular (e.g., amoeba).
    • Contain membrane-bound organelles, including nuclei, endoplasmic reticulum, Golgi apparatus, and more.
    • DNA is contained within a defined nucleus.
    • Exhibit various structures for movement, such as flagella (ex: sperm) and cilia (for attachment).
