History of Cell Biology

Cell biology

A cell is the smallest unit of life. Cell biology is a field of biological science in which we study the structural and functional properties of a cell.

History of cell biology:

  • In 322-384 B.C. Aristotle and Paracelsus concluded that “all animals and plants, however, complicated, are constituted of a few-element which are repeated in each of them”. They referred to these macroscopic structures of an organism such as roots, flowers, and leaves or segments.
  • In 1485 invention of magnifying lenses, the new world of the microscope was discovered by Da Vinci
  • A swiss biologist Cornard Genser (1516-1565) published the result of his students, a study on the structure group of protists called foraminifera.

Further development of cell biology was associated with the development of optical lenses and microscopes (compound microscopes).

Growth of cell biology during

  1. 16th and 18th centuries
  • In 1590 by Francis Janssen and Zacharias Janssen, the first useful compound was invented with 10X and 30X. These microscopes were called “flea glasses”.
  • In 1609 Galileo Galilei (1564-1642) invented the simple microscope.
  • Marcello Malpighi (1628-1694) was the first to use a microscope to examine thin slices of animal tissues from different organs such as the brain, liver. He also had studied on plant tissue and described the structural unit as “utricles”.
  • In 1665 Robert Hooke (1635-1703) named these structural units as cell (Latin: cella – hollow space).
  • Anton van Leeuwenhoek (1632-1723) who was a microbiologist, was the first to observe living cells from rainwater collection in tubes. His sketches included numerous bacteria such as bacilli, cocci, and spirilla.

 

  1. 19th century
  • Mirbel, 1807: all plant tissues were also composed of cells
  • Rene Dutrochet, 1824: all animal and plant tissues were “aggregates of globular cells”
  • Robert Brown, 1831 discovered nucleus
