    Study Notes

    Cell Biology

    • Cell is the basic unit of life.
    • Cells are important for an organism's survival.

    Types of Cells

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

    Prokaryotic Cells

    • Characterized by the absence of a true nucleus.
    • Examples of prokaryotic cells include bacteria and archaea.

    Eukaryotic Cells

    • Defined as cells containing an organized nucleus and organelles enveloped by membrane-bound organelles.
    • Examples of eukaryotic cells include animals, plants, fungi, and protists.

    Cell Theory

    • The cell theory has three postulates that explain the structure and function of cells.

    Discovery of Cells

    • Robert Hooke was the first person to observe cells as microscopic structures.
