About This Quiz & Worksheet

Cell membranes can be selectively permeable to allow molecules and ions to pass through them. This quiz/worksheet combo will help test your understanding of how and why membrane permeability occurs. Some concepts you'll be assessed on are the purpose of vesicles and the composition of cell membranes.

Quiz & Worksheet Goals

In this assessment, you'll be tested on the following terms:

  • Hydrophilic
  • Vesicles
  • Selective permeability
  • Phospholipids

Skills Practiced

  • Defining key concepts - ensure that you can accurately define main phrases, such as hydrophilic
  • Information recall - review the number of phospholipid layers that make up a cell membrane
  • Making connections - use your understanding of the number of selectively permeable membranes contained in an egg

Additional Learning

To learn more about cell membranes, review the accompanying lesson titled Selectively Permeable Membranes: Definition & Examples. This lesson covers the following concepts:

  • Difference between active and passive transport
  • Definition of a protein channel
  • Physiology of a sodium potassium channel
  • How a cell removes large waste particles using vesicles
