membranes and concentration

molecules repelled by water

molecules attracted to water

proteins attatched to surface of membranes

proteins embedded in the phospholipid bilayer

a molecules that has a polar head and two non-polar tails, keeps membrane fluid at low temperatures

double layer of phospholipids that make up a membrane

membrane that surrounds the cytoplasm

the uptake of large molecules into the cell by surrounding them with plasma membrane to form vesicles

the export of large molecules from the cell by the fusion of vesicles with the plasma membrane

cells that have gained water and become tight

cells that have lost water and become floppy

has the same concentration of solute as inside the cell

solution that has a higher concentration of solutes than inside the cell

causes cell to lose water and become flaccid

solution that has a lower concentration of solutes than inside the cell

cell will gain water and become turgid
