<strong>Lab</strong> 6: Diffusion<br />
Questions<br />
1. Which dye diffused the fastest in corn syrup? In your chosen material?<br />
2. Does the rate of diffusion correspond with the molecular weight of the dye?<br />
3. Does the rate of diffusion change over time? How might this affect your calculated diffusion<br />
rate compared to the actual diffusion rate?<br />
4. Cells receive vital nutrients and rid toxic waste with the help of the circulatory system. What is<br />
the critical distance a cell must maintain from a capillary (the point of nutrient/waste exchange)<br />
in order to survive? Explain the role diffusion plays in this process.<br />
5. Describe why the medium the dyes diffuse through can affect the rate of diffusion. How does<br />
this relate to nutrient transport into cells?<br />
