1. Cell Transport Chris French, James Graessle, Mo Hnaino, Megan Pokal

2. Vocab Diffusion: Process by which molecules tend to move from an area where they are more concentrated to an area where they are less concentrated. Passive Transport: Movement of material down the concentration gradient. Active Transport: Energy-requiring process that moves material across a cell membrane against a concentration difference.

3. Osmosis: Diffusion of water through a selectively permeable membrane.(passive) Endocytosis: Process by which a cell takes material into the cell by infolding of the cell membrane.(active) Exocytosis: Process by which a cell releases large amounts of material.(active) Isotonic: When the concentration of two solutions is the same. Hypertonic: When comparing two solutions, the solution with the greater concentration of solutes

4. Hypotonic: When comparing two solutions, the solution with the lesser concentration of solutes. Facilitated Diffusion: Movement of specific molecules across cell membranes through protein channels. Channel Protein: Form channels to allow specific molecules to flow through. Carrier Protein: Change shape to allow a substance to pass through the membrane.
