Description

Overview:

This minds-on analysis and discussion activity helps students understand that cell size is limited by the very slow rate of diffusion over any substantial distance and the insufficient surface-area-to-volume ratio for larger cells. In addition, students calculate why these problems do not apply to long slender cells or parts of cells (e.g. the axons of neurons that extend from your spinal cord to your foot). To maximize student participation and learning, I recommend that you have your students complete the questions individually or in pairs and then have a whole class discussion.
