Study Notes
Cell-Structure and Function
- Every organism starts life as a single cell, which divides and redivides to form tissues and eventually, organs.
- Cells are the smallest structural and functional unit of life, visible only with a microscope.
Discovery of Cell
- Robert Hooke (1665) observed dead cells resembling honeycomb-like structures in cork, and termed them as "cells".
- Antony Van Leeuwenhoek (1674) was the first to observe living cells in pond water.
- Robert Brown (1831) discovered the nucleus.
- J.E.Purkinje (1839) coined the term "protoplasm" to describe the living matter present inside cells.
- Rudolf Virchow (1855) established that all cells arise from pre-existing cells, stating "omnis cellula e cellula".
