Cell Transport Vocab
| Term | Definition |
|---|---|
| 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 |
