LESSON 1: CELL BIOLOGY

CELL BIOLOGY

STUDY OF CELL STRUCTURE, FUNCTION, AND BEHAVIOR AS THE FUNDAMENTAL UNITS OF LIFE

CELL

FROM THE LATIN WORD “CELLA”

SMALL ROOM

THE LATIN WORD “CELLA” MEANS

CELL

BASIC STRUCTURAL, FUNCTIONAL, AND BIOLOGICAL UNIT OF ALL KNOWN ORGANISMS

CELL

SMALLEST UNIT OF LIFE

CELL

BUILDING BLOCKS OF LIFE

CELL THEORY

STATES THAT CELLS ARE THE BASIC BUILDING BLOCKS OF ALL LIVING THINGS AND THAT ALL LIFE COMES FROM PRE-EXISTING CELLS

CELL THEORY

PROPOSED IN THE 19TH CENTURY BY MATTHIAS JAKOB SCHLEIDEN AND THEODOR SCHWANN, THEN LATER EXPANDED BY RUDOLF VIRCHOW

FIRST TENET OF THE CELL THEORY

ALL LIVING ORGANISMS ARE COMPOSED OF ONE OR MORE CELLS

SECOND TENET OF THE CELL THEORY

THE CELL IS THE BASIC UNIT OF STRUCTURE AND ORGANIZATION IN ORGANISM

THIRD TENET OF THE CELL THEORY

CELL ARISE FROM PRE-EXISTING

SPONTANEOUS GENERATION

PROPOSED BY ARISTOTLE

SPONTANEOUS GENERATION

DEBUNKED BY LOUIS PASTEUR

SPONTANEOUS GENERATION

BELIEF THAT NON-LIVING THINGS CAN MAKE LIVING ORGANISMS

LOUIS PASTEUR

HE BOILED BEEF BROTH TO KILL ANY LIVING GERMS. IT STAYED CLEAR AND FRESH FOR A LONG TIME BECAUSE AIR COULDN’T PASS THROUGH THE CURVED NECK

LOUIS PASTEUR

INVENTED PASTEURIZATION

ROBERT HOOKE

ENGLISH SCIENTIST WHO SLICED A VERY THIN SLICE OF A CORK FROM AN OAK CORK AND OBSERVING IT UNDER HIS OWN CRUDE MICROSCOPE

ROBERT HOOKE

HE SAW ROOMS WHICH REMINDED HIM OF MONASTERY

ROBERT HOOKE

DISCOVERED CELL WALL

ROBERT HOOKE

HE BEGAN THE SCIENTIFIC STUDY OF CELLS (CELL BIOLOGY) IN THE 17TH CENTURY

ANTONIE VAN LEEUWENHOEK

DUTCH NATURALIST WHO GRINDS LENSES

ANTONIE VAN LEEUWENHOEK

DISCOVERED ANIMALCULES FROM A DROP OF RAINWATER

ANIMALCULES

“SMALL ORGANISM”

ANIMALCULES

BACTERIA

ANIMALCULES

UNICELLAR ORGANISM

ANTONIE VAN LEEUWENHOEK

HE OBSERVED MULTICELLULAR ORGANISM IN POND WATER

ANOTNIE VAN LEEUWENHOEK

FIRST TO DOCUMENT MICROSCOPIC OBSERVATIONS OF MUSCLES, FIBERS, BACTERIA, SPERMATOZOA, RBC, CRYSTALS IN GOUTY TOPHI, AND BLOOD FLOQ IN CAPILLARIES

ANTONIE VAN LEEUWENHOEK

ROBERT BROWN

DISCOVERED THE NUCLEUS

FELIX DUJARDIN

FRENCH BIOLOGIST BORN IN TOURS

FELIX DUJARDIN

DISCOVERED THE SARCODE, WHICH LATER BECAME “PROTOPLASM”

PROTOPLASM

SEMI-TRANSPARENT LIVING SUBSTANCE THAT MAKES UP THE INSIDE OF A CELL

CYTOSOL

CELL FLUID

MATTHIAS JAKOB SCHLEIDEN

GERMAN BOTANIST AND CO-FOUNDER OF CELL THEORY, ALONG WITH THEODOR SCHWANN AND RUDOLF VIRCHOW

MATTHIAS JAKOB SCHLEIDEN

CONCLUDED THAT ALL PLANTS ARE MADE UP OF CELLS

THEODOR SCHWANN

GERMAN PHYSICIAN AND PHYSIOLOGIST

THEODOR SCHWANN

ANIMALS ARE COMPOSED OF CELLS

RUDOLF LUDWIG CARL VIRCHOW

GERMAN PHYSICIAN, ANTHROPOLOGIST, PATHOLOGIST, PREHISTORIAN, BIOLOGIST, WRITER, EDITOR, AND POLITICIAN

RUDOLF LUDWIG CARL VIRCHOW

FATHER OF MODERN PATHOLOGY

RUDOLF LUDWIG CARL VIRCHOW

FOUNDER OF SOCIAL MEDICINE (POPE OF MEDICINE)

RUDOLF LUDWIG CARL VIRCHOW

STATED THAT “CELLS ARISE FROM PRE-EXISTING CELLS” IN HIS ESSAY CELL PATHOLOGY

OMNIS CELLULA E CELLULA

“CELLS ARISE FROM PRE-EXISTING CELLS” IN LATIN

APOPTOSIS

PROGRAMMED CELL DEATH

TISSUE

MADE UP OF CELLS

ORGAN

MADE UP OF TISSUES
