Carl Linnaeus
Best known for his Theory of Evolution
Charles Darwin
Father of Genetics
Gregor Mendel
Discovered the
molecular

“CELL”
Robert Hooke
- All organisms are
made up of cells. - The basic unit of
life is the cell.
Matthias Schleiden and Theodore Schwann
- Cells arise from
preexisting cells.
Rudolf Virchow and Robert Remak
_____ are the smallest, basic
unit of life that is
responsible for all of life’s processes.
Cells
______ are the structural,
functional, and biological
units of all living beings.
Cells
The _____ and the ______are the main components that function to provide support and structure to the organism.
cell wall
and cell membrane
General Functions of a cell
- Provides Support and Structure
- Allows Transport of Substances
- Acquisition and Utilization of Energy
- Responsiveness to their Environment
_____ is needed by cells to drive most of the chemical reactions and other functions in the organism’s body.
Energy
______ require less energy and fewer resources to transport molecules across shorter distances.
Smaller cells
Smaller cells have a _________,
allowing them to process energy more efficiently.
higher metabolic rate
(1625) created the first microscope
Galileo Galilei
(1665) coined the name “cell”
Robert Hooke
(1670) improved microscope lenses, was the first to discover and describe microorganisms, “animalcules”
Anton van Leeuwenhoek
(1804) proved cells were independent - each has its cell wall
Karl Rudolphi and Johann Heinrich Friedrich Link
(1833) discovered the nucleus in plant cells
Robert Brown
(1838-1839) Proposed that all plant and animal tissues are composed of cells, leading to the foundational statements:
- All living organisms consist of one or more cells.
- The cell is the basic unit of structure for all living organisms.
Matthias Schleiden and Theodore Schwann
(1845) Revised the cell theory to state that cells are the basic functional and structural unit of life.
Carl Heinrich Braun
(1855) Introduced the concept “Omnis cellula e cellula,” meaning cells only arise from other cells.
Rudolf Virchow
it is just an editorial piece, not a scientific paper
Rudolf Virchow to Robert Remak
remaks work was not credited
what experiment helped them arrive “omnis cellula e cellula”
redi’s experiment, the stepping stone to spontaneous generation theory
