Instructional Ideas
  • Research other ways the body uses signal transduction pathways to communicate messages
Classroom Considerations
  • Class must have access to a computer, Internet, and a projection system
  • Assumes learners understand signal transduction pathways
  • Lesson is part 19 in a series of 37
  • Shows, very simply, how multicellular organisms and single-celled organisms communicate in a similar way
  • Describes steps of signal transduction pathway in an easy-to-follow manner
  • Great visuals to help learners understand cell communication
  • None
