Cell Transport Vocab

passive transport no energy required, move due to gradient, move to equalize gradient (Diffusion, Osmosis, Facilitated Diffusion)
osmosis fluid flows to lower solute concentration, often involves movement of water (in or out of cell)
facilitated diffusion differently permeable membrane, channels help molecule or ions enter/leave the cell, no energy is used
active transport molecular movement, requires energy (against gradient) sodium-potasium pump
hypotonic solution solution has a lower concentration of solutes and higher concentration of water then inside the cell, result- water moves inside the cell causing swelling/bursting open
hypertonic solution solution has higher concentration of solutes and lower concentration of water, result- water moves inside the cell to the solution(cell shrinks)
isotonic solution concentration of solutes is equal to concentration inside the cell, results- water moves equally in both directions and cell remains the same(equalibrium)
endocytosis movement of a large material into cells, phagocytosis (cell eating) or pinocytosis (cell drinking)
exocytosis cell discharges materials made, example- stomach cells discharging protective mucus and/or stomach acid
