Transport Across Cell Membranes

Materials don't need a password to move through cell membranes! Learners explore how cells move materials across the cell membrane. The video then teaches the detailed workings of both passive transport (specifically diffusion, facilitated diffusion, and osmosis) and active transport (specifically the sodium potassium pump, endocytosis, and exocytosis).

Instructional Ideas

  • Pause video at 5:50 and ask learners to explain why placing salt on a slug kills it
Classroom Considerations

  • Consider showing the cell membrane video in the series first
  • To view the video, you need a computer, Internet access, and a projection system
  • Part 35 in a series of 37
Pros

  • Includes concept map, slideshow, link to another video on cell membranes, and two review worksheets
  • Provides simple and effective explanations of these processes with great examples, such as why slugs die when salt is on them
  • Ties each process back to where this may happen in your body and the outcome
Cons

  • None
