UNDERSTANDING TRANSPORT AND THE CELL MEMBRANE DIRECTIONS: If you do not have colored pencils please label the drawing with the letter indicated in the directions. (Example: Oxygen is green so use the letter G) and then answer the questions at the end of the assignment. The cell membrane is responsible for moving materials into and out of the cell. There are two types of transport that can occur across the membrane: passive transport and active transport. Passive transport does not require energy and includes the processes of osmosis, diffusion and facilitated diffusion. The graphic shows the phospholipid bilayer and embedded proteins, the two main components of the cell membrane. Phospholipids are made of hydrophilic (water-loving) heads and hydrophobic (water- hating) tails. The phospholipids are arranged opposite to each other, with the heads pointing toward the cell’s environment and the tails aligning to each other. Color all the phospholipids (c) of the membrane red.
