Chapter 5 Study Guide Cell Transport

Membrane Structure: How are macromolecules arranged to form a membrane? A. I can identify the parts of the plasma membrane from diagrams. B. I can list the function of each part of the plasma membrane.

C. I can show how all of the parts of the plasma membrane work together to make it selectively permeable.

Semipermeable: ________________________________________________________________________ Phosphate head: Lipid tail: Double layer: Passive Transport: How do cells transport substances across a membrane without using energy? A. I can explain what passive transport is and why cells do it. B. I can list and describe examples of passive transport. C. I can predict what will happen to plant and animal cells when placed in the

following solutions: hypotonic, hypertonic, and isotonic. D. I can write differences between the three examples of passive transport.
