Cellular Transport Graphic Organizer Type of Transport Description Explanation Name: ____________________________ Date: ____________ Illustration Passive Transport Diffusion Osmosis H2O hypotonic - hypertonic - isotonic - Facilitated Diffusion Example Type of Transport Description Explanation Active Transport Protein Pumps Endocytosis Exocytosis Illustration Example Type of Transport Description Explanation Illustration Gas exchange in the lungs Diffusion Passive Transport The movement of small, uncharged molecules directly through the phospholipid bilayer The movement of particles across the cell membrane from an area of high concentration to an area of low concentration Example Gas exchange during photosynthesis Osmosis The movement of water molecules Water balance by fish through special membrane proteins hypotonic – solution that has a higher H2O concentration of water compared to a cell’s interior hypertonic - solution that has a lower concentration of water compared to a cell’s interior isotonic - solution that has the same concentration of water compared to a No energy is required from the cell cell’s interior Facilitated Diffusion The movement of small, sometimes charged, molecules through membrane protein channels Glucose uptake (blood sugar) by cells in the body Type of Transport Description Explanation Active Transport Protein Pumps The movement of particles across the cell membrane from an area of low concentration to an area of high concentration Also used to move many particles at once or very large particles Energy is required The movement of small particles into an area where they are more concentrated using membrane proteins Illustration Example Sodium-Potassium pumps in every neuron Particles can be pumped into a cell or out of a cell Endocytosis The inward movement of numerous White blood cell engulfing a bacterial cell or large particles by forming a vesicle with the cell membrane Exocytosis The outward movement of numerous or large particles by forming a vesicle with the cell membrane Nerve cells communicating (sending a nerve impulse)
