TYPE OF MOVEMENT PICTURE DESCRIPTION PHAGOCYTOSIS A type of endocytosis in which large particles are taken in by the cell ENDOCYTOSIS The process of taking material into the cell by means of pockets in the membrane EXOCYTOSIS The removal of large amounts of materials from a cell PINOCYTOSIS A process by which certain cells can engulf and incorporate droplets of fluid TYPE OF MOVEMENT PICTURE WHAT MOVES? CONCENTRATION GRADIENT ENERGY REQUIRED? DIFFUSION PARTICLES IN WATER HIGH TO LOW NO OSMOSIS WATER MOLECULES ONLY HIGH TO LOW NO FACILITATED DIFFUSION CARRIER HIGH TO PROTEINS MOVE LOW MOLECULES ACROSS CELL MEMBRANE NO ACTIVE TRANSPORT CARRIER PROTEIN USES ATP TO MOVE MOLECULES ACROSS CELL MEMBRANE LOW TO HIGH YES SOLUTION & INITIAL CELL CONCENTRATION OF SOLUTE OUTSIDE THE CELL CONCENTRATION OF SOLUTE INSIDE THE CELL WHICH WAY WILL WATER MOVE? HYPOTONIC SOLUTION LOWER HIGHER INTO CELL ISOTONIC SOLUTION SAME SAME INTO & OUT OF CELL HYPERTONIC SOLUTION HIGHER LOWER OUT OF THE CELL PICTURE OF FINAL CELL
