Study Notes

Cell Discovery and Theory

  • Robert Hooke is credited with the discovery of the cell in 1665.
  • Hooke observed cork under his microscope and saw tiny pockets or compartments, which he called "cells."
  • Lorenz Oken believed that all living beings originate from or consist of vesicles or cells.
  • Jean-Baptist de-Lamarck expressed the idea that no body can have life if its constituent parts are not cellular tissue or are not formed by cellular tissue.
  • Matthias Jakob Schleiden, a German botanist, and Theodor Schwann proposed the Cell Theory.
  • Robert Brown reported the presence of a nucleus in the cell in 1831, which changed the understanding of cells.

Cell Theory Components

  • The three basic parts of the cell according to the Cell Theory are:
    • Cellular tissue
    • Vesicles
    • Cells
