Compound Light Microscope
Allows light to pass through specimen and uses z lenses to form an image.
Uses beams of electrons that are focused by magnetic fields. Also it is uses to study cells and cell structures.
1.) all living things are made up of cells.
2.) cells are the basic units of structure and function in living things.
3.) new cells are produced from existing cells.
Anton Von Leeuwenhoek
1st to observe living microorganisms using a simple microscope.
He created the word cells to describe the building blocks of life.
doesn't include DNA in the nuclei
center of an atom which includes the protons and neutrons in the cell also includes the cells genetic material.
cell membrane (flexible barrier that surrounds all cells)
part of the cell outside the nucleus
enclose their DNA in nuclei larger and more complex cells
Scanning Probe Microscope
device capable of producing images of individual atoms and molecules on surfaces of materials
