    Study Notes

    Development of Cell Theory

    • Anton van Leeuwenhoek, a Dutch scientist, is considered the father of modern microbiology for his discovery of microorganisms (bacteria) using a microscope in the 1600s.
    • He observed "animacules" (bacteria) in dental scrapings, which led to the discovery of microorganisms.

    Discovery of Cells

    • Robert Hooke, an English scientist, discovered cells by observing a cork under a microscope and observing the cell structure.
    • He named them "cells" because the cell structure resembled little rooms (cellula in Latin) in a monastery.

    First Tenet of Cell Theory

    • The first tenet of cell theory states that the cell is the basic unit of structure in life.
    • This was developed through observations of bacteria, plants, and animals, which all have cells as their basic structure.

    Contributions of Matthias Schleiden and Theodor Schwann

    • Matthias Schleiden, a German botanist, observed that all plants have the same microscopic structure (cells) in the 1830s.
    • Theodor Schwann, a German scientist, observed that all animals have the same microscopic structure (cells) in the 1830s.
    • They concluded that all living organisms are composed of cells, which is the second tenet of cell theory.

    Third Tenet of Cell Theory

    • The third tenet of cell theory states that all cells come from preexisting cells.
    • This was developed through the work of Rudolph Virchow, who observed that cells divide and reproduce, and Louis Pasteur, who disproved the theory of Abiogenesis through his Swan-Neck Bottle experiment.

    Refutation of Abiogenesis

    • Abiogenesis is the theory that life can arise from non-living matter spontaneously.
    • Louis Pasteur's Swan-Neck Bottle experiment showed that microorganisms in the air can contaminate a sterilized broth, disproving Abiogenesis.
    • This experiment established the third tenet of cell theory, that all cells come from preexisting cells.
