The cell was discovered by Robert Hooke in 1665. He used a self-designed compound microscope to observe a thin slice of cork (bark of oak tree) and saw small, box-like compartments which he called 'cells' (from the Latin 'cellula' meaning small room). This was the first time the word 'cell' was used in biology.
Cell was discovered by Robert Hooke in 1665 while observing cork.
Hooke's book: Micrographia (1665) — first detailed microscopy publication.
Hooke saw dead cell walls (empty compartments) and called them 'cells'.
Anton van Leeuwenhoek first observed living cells (bacteria, RBCs) in 1674.
Cell Theory: Schleiden (1838) + Schwann (1839) + Virchow (1855).

Who Discovered the Cell? • Discoverer: Robert Hooke • Year: 1665 • Book: Micrographia (1665) • What he observed: Dead cells (walls) of cork using a compound microscope • What he saw: Small, empty, box-like compartments • Name given: 'Cell' (from Latin 'cellula' = small room)
Timeline of Cell Discovery:
| Year | Scientist | Discovery |
|---|---|---|
| 1665 | Robert Hooke | Discovered cells in cork; coined term 'cell' |
| 1674 | Anton van Leeuwenhoek | First observed living cells (bacteria, RBCs) using single-lens microscope |
| 1831 | Robert Brown | Discovered the nucleus in plant cells |
| 1835 | Félix Dujardin | Observed cytoplasm (called sarcode) |
| 1838 | Matthias Schleiden | All plants are made of cells (Cell Theory — plants) |
| 1839 | Theodor Schwann | All animals are made of cells (Cell Theory — animals) |
| 1855 | Rudolf Virchow | 'Omnis cellula e cellula' — every cell arises from a pre-existing cell |
Cell Theory (3 Principles):
Robert Hooke — Key Facts: • Born: 28 July 1635, Isle of Wight, England • Died: 3 March 1703 • Book: Micrographia (1665) — illustrated science book; first detailed microscopy work • Hooke did NOT observe living cells — he saw dead cell walls of cork
Aton van Leeuwenhoek: • Often called 'Father of Microbiology' • First to observe bacteria, protozoa, RBCs (living cells) • Used single-lens microscopes with very high magnification
NCERT: Class 8 Science Chapter 8 — Cell; Class 9 Science Chapter 5 — The Fundamental Unit of Life
Robert Hooke discovered the cell in 1665. He observed a thin slice of cork under a compound microscope and saw small, box-like compartments, which he named 'cells' (from Latin 'cellula' = small room). He published this in his book Micrographia (1665). Hooke observed dead cell walls. Anton van Leeuwenhoek later (1674) was the first to observe living cells. Cell Theory was formulated by Schleiden (1838), Schwann (1839), and Virchow (1855).
