7.1 Life is Cellular
Lesson Objectives
State the cell theory
Describe how the different types of microscopes work

Cell Theory
The scientific theory describing cells, e.g. the cell as the basic unit of living organisms,
and that all cells arise only from pre-existing, living cells
All living things are made up of one or more cells.
The cell is the structural and functional unit of all living things; Cells are the basic
unit of life.
Cells come from pre-existing cells through the process of division.

, Theodor Schwann: all
animals are made of
Matthias Jakob Schleiden Rudolf Virchow: all cells
cells
(Botanist): all plants are come from pre-existing
made of cells cells
Modern Cell Theory
Cells carry genetic material during cell division
All cells of the same species are the same in regard to chemical composition.
Energy flow occurs in cells
What invention best helped scientists to develop the cell theory?
A: Microscopes
Anton van Leeuwenhoek’s microscope was 300x more magnified than Robert Hooke’s
