Prokaryotes

________ do not have a nucleus while eukaryotes do.

Lyse

________: to break open a cell by exposure to chemicals, enzymes, or sound waves.

Eukaryotes

________ have membrane- bound organelles while prokaryotes do not.

Centrifugation

________: using the centrifugal force to separate different parts of the cell based on density and size.

Homogenization

________: blending together the subcellular contents.

Epithelial cells

cells that line the outer or inner surfaces of organs or tissues

Endothelial cells

cells that line areas of the cardiovascular system, specifically blood vessels
