How does the cell theory describe the levels of organization of living organisms?
It says that it all begins with the cell.
Suppose you discovered a new type of plant. Applying the cell theory, what can you say for certain about this organism?
It:
Has cells
It's basic structure is cells
It came from preexisting plant cells.
Compare the sources of the beam in a light microscope to that in an electron microscope.
Light micro. use light, and electron use beams of electrons.
Explain the difference between a scanning electron microscope and a transmission electron microscope and their uses.
Scanning scan surafces to see the cell's 3D shape. Transmission stud the insides of cells.
Evaluate the microscope's impact on the study of cells.
They helped study cells because you could see them up close.
Describe the history of microscopes.
Microscopes started out as simple light microscopes, moving on to electron microscopes like scanning el. mic., trasmission em, and scanning tunneling microscopes.
Describe the differences between a prokaryotic and a eukaryotic cell, and identify their parts.
P: don't have membrane-bound organelles
usually unicellular
E: are mem. bound and generally multicellular
p: have ribosomes, DNA, cell walls
e: have only nuclei, chromosomes, ERs, etc.
