Study Notes
Cell Overview
- Cells are the fundamental structural and functional units of living organisms.
- Often referred to as "building blocks of the body," similar to bricks in a structure.
Discovery of the Cell
- Robert Hooke observed cork slices in 1665 using a simple microscope.
- He noted honeycomb-like structures, which he termed "cells," although these were actually dead cells.
- Living cells were first observed with the advent of advanced microscopes featuring high magnification.
Cell Theory
- In 1838, German biologists Schleiden and Schwann formulated the cell theory.
- The cell theory was further developed by Virchow.
- Key components of the cell theory include:
- All living organisms are composed of cells.
- Cells are the basic units of structure and function in life.
- New cells are produced from existing cells through division.
- The arrangement of cells within an organism determines its overall structure and function.
