★ father and son lens grinder and
spectacle maker from Netherlands
Hans and Zacharias Janssen
★ figured out how to align and
combine lenses to view things far
away or up close
Hans and Zacharias Janssen
★ believed to be the first investigator to invent the compound microscope
Hans and Zacharias Janssen
★ discovered the cell after examining under a compound microscope, very thin slices of cork tissue from a dead piece of wood
ROBERT HOOKE
★ saw the CELL WALL
★ observations were published in
MICROGRAPHIA
ROBERT HOOKE
What is the MICROGRAPHIA?
Micrographia, a book filled with drawings and descriptions of the organisms he viewed under the recently invented microscope.
★ Dutch tradesman and craftsman with no formal education
★ reported the discovery of forms
of life including:
○ algae
○ nematodes
○ protozoans
ANTONI VAN LEEUWENHOEK

ROBERT HOOKE
Who discovered algae, nematodes, and protozoans?
ANTONI VAN LEEUWENHOEK
French biologist who first
described cell division in plants?
BARTHÉLEMY CHARLES JOSEPH
DUMORTIER
★ introduced the term NUCLEUS, an opaque spot near the middle of the cell
ROBERT BROWN
★ made the first accurate
description of NUCLEOLUS
GABRIEL GUSTAV VALENTIN
★ proposed that every structural
element of PLANTS is composed of cells
MATTHIAS SCHLEIDEN
★ parts of ANIMALS are made up of
cells
THEODOR SCHWANN
➔ was proposed by ARISTOTLE
➔ Life can originate from non-living
materials
➔ disproved by LOUIS PASTEUR
and FRANCESCO REDI
SPONTANEOUS GENERATION
- All living things are made up of
cells. - The cell is the structural and
functional unit of all living things - All cells come from pre-existing
cells: omni cellula e cellula
CLASSICAL TENETS OF CELL
THEORY
- All living things are made up of
cells. - The cell is the structural and
functional unit of all living things - All cells come from pre-existing
cells: omni cellula e cellula. - All cells contain hereditary
information which is passed from
cell to cell during cell division. - All cells are basically the same in
chemical composition and
metabolic activities. - All basic chemical and
physiological functions are carried
out inside the cells - Cell activity depends on the
activities of subcellular structures
within the cell.
MODERN CELL THEORY

information which is passed from
cell to cell during cell division.
