Osmosis: movement of water molecules from an area of higher concentration to an area of lower concentration through a semipermeable membrane.
Osmosis calculations: equation is π=iMRT π is not equal to 3.14159 in this situation. π stands for the osmotic pressure and is usually expressed in the pressure unit of atmospheres.
Diffusion: the random movement of molecules from an area of higher concentration of those molecules to an area of lower concentration.
Prokaryotic cells: unicellular organisms that lack organelles or other internal membrane-bound structures.
Eukaryotic cells: organisms whose cells have a nucleus enclosed within membranes, unlike prokaryotes.
Mitosis: cell division in which the nucleus divides into two nuclei containing the same number of chromosomes with an end result of two identical cells.
Stem cells: an undifferentiated cell that is capable of dividing and giving rise to one or more distinct types of specialized cells.
