The History of the Cell
(Life Science 3rd edition)
The first person to observe cells was Robert Hooke. Hooke was an English
scientist. He used a compound microscope to look at thin slices of cork. Cork is
found in some plants. The cork seemed to be made up of many small boxes.
Each box looked like a small room with walls around it, like the picture above.
The boxes reminded Hooke of the rooms in which monks slept called cells.
Hooke named the structures that made up the cork, “cells”. All living things are
made up of one or more cells. Cells are the building blocks of all living things.
Hooke saw only dead plant cells in cork. Anton Van Leeuwenhoek was
the first person to observe living cells. In 1675, he saw a single celled organism in
a drop of pond water. These living things were microscopic and could not be
seen without a microscope.
By 1800, better microscopes were being made. Many plant and animal
cells were being studied. Two scientists, Matthias Schleiden and Theodor
Schwann had many ideas about cells. These ideas were put together in what is
known as the cell theory.
The Cell Theory states:
- All living things are made up of one or more cells.
- Cells are the basic units of structure in living things, and cells carry on all
life processes.
- Cells come only from other living cells.
