Intro to the Cells
Cell Theory:
• All living organism are composed of one or more cells
• Cells are the smallest living thing
• Cells can. Only arise from the division of previous existing
cells
Microscope Invention:
• 100AD: Glass Invented in
Rome
• 1250AD: Wearable lenses
(Spectacles) invented in
Italy and England
• 1608: Lipperhey and Janssen
(spectacle makers) created
the compound microscope
- MAJOR INNOVATION
• 1660s: Using this, Robert T
Hooke discovered "cells" in
cork
• Allowed the fundamental results which is the discovery of
cells and its organelles
• Light microscope alone is insufficient to resolve many cellular
structures
Fluorescence Microscopy:
• Can show us the location of specific molecule in the cell
• Confocal: Uses laser to show a single plane in the image
• It works by manipulating the position of electrons from↳
one. Orbital to another
• Electrons in a fluorophore can be "excited" by specific
wavelengths of light
