CELL THEORY - SAN JUAN
Storyboard-Text
- HI BRO. HOW'S SCHOOL TODAY?
- WELL.. IT'S WAS FINE. IVE LEARNED SOMETHING NEW.
- WOW! CAN YOU SHARE IT WITH ME?
- YEAH, OF COURSE. IT'S ABOUT FORMULATION OF CELL THEORY.
- WOW.. WHAT DO YOU CALL THESE TINY COMPARTMENTS?
- HOOKE NAMED THESE COMPARTMENT CELLS.
- DID YOU KNOW THAT IN 1665, AN ENGLISH SCIENTIST, ROBERT HOOKE, EXAMINED A THIN SLICE OF CORK WAS COMPOSED OF MANY TINY COMPRTMENTS WHICH RESEMBLED LITTLE ROOMS WITH SURROUNDING WALL.
- EHHH? WHY DID HE NOT PURSUE IT?
- WELL BECAUSE THE CELLS THAT HOOKE OBSERVED WERE NOT LIVING.
- AM I RIGHT?
- BUT HOOKE DID NOT PURSUE HIS INVESTIGATION OF THE CELL CONTENT.
- HE DISCOVERED FREE CELLS AND OBSERVED THE NUCLEUS WITHIN SOME RED BLOOD CELLS. LEUWENHOEK WAS A CONTEMPORARY OF ROBERT HOOKE. HE HAD MOR SUCCESS IN LIVING CELL IN ACTION DESPITE HIS SMALLER, SIMPLER, HANDLED MICROSCOPES.
- AMAZING..
- IN 1674, THE DUTCH INVEENTOR ANTOINE VAN LEUWENHOEK OBSERVED RED BLOOD CELLS, SPERMS AND A MYRIAD OF SINGLE-CELLED ORGANISMS IN POND WATER.
- THEY ARE ALL SMART...
- I KNOW RIGHT.
- IN 1838, MATTHIAS SCHLEIDEN, A GERMAN BOTANIST, STATED THAT ALL PLANTS ARE COMPOSED OF CELLSS. WHICH IS TRUE. AND IN 1839, THEODOR SCHWANN, A GERMAN ZOOLOGIST, CONCLUDED THAT ALL ANIMALS ARE COMPOSED OF CELLS WHICH IS ALSO TRUE.
