(polar or charged) 38 Passive transport without help of proteins 39 What is diffusion? 40 Direction molecules diffuse across a cell membrane 41 What is high to low concentration? 42 Water movement across a cell membrane 43 What is osmosis? 44 Point where molecules are evenly distributed 45 What is equilibrium? 46 Water pressure exerted against plant cell walls 47 What is turgor? 48 Required by cells when materials move by active transport 49 What is ATP or energy? 50 Direction of movement across a membrane during active transport 51 What is low to high concentration? 52 membrane “pumps” 53 What are transport proteins? 54 Membrane pumping system that keeps Na+ ions concentrated 55 What is the sodiumpotassium pump? 56 57 Process where cells “drink” droplets of liquid 58 What is pinocytosis? 59 Condition inside cell if outside of cell is hypotonic 60 What is hypertonic? 61 A unicellular organism’s organelle which pumps out water 62 What is a contractile vacuole? 63 Direction of water movement when the solute concentration outside the cell is lower than inside 64 What is water moving into the cell? 65 Molecules soluble in this can diffuse through the cell membrane 66 What are lipids? 67 Condition inside cells when plant cells lose turgor pressure and wilt 68 What is plasmolysis? 69 70 Transport 71 Kinetic energy of molecules or a concentration gradient 72 What makes passive transport possible? 73
