Diffusion | Process by which molecules tend to move from an area where they are more concentrated to an area where they are less concentrated |
Equilibrium | When the concentration of a solute is the same throughout a solution |
Osmosis | Diffusion of water through a selectively permeable membrane |
Isotonic | When the concentration of two solutions is the same |
Hypertonic | when comparing two solutions, the solution with the greater concentration of solutes |
Hypotonic | when comparing two solutions, the solution with the lesser concentration of solutes |
Lipid bilayer | it gives the cell membranes a flexible structure that forms a strong barrier between the cell and it’s surroundings |
Concentration | it is the mass of solute in a given volume of solution |
Cell Theory | idea that all living things are composed of cells, cells are the basic units of structure and function in living things, and new cells are produced from existing cells |
Eukaryotes | organism whose cells contain nuclei |
Prokaryotes | unicellular organism lacking a nucleus |
