A&P I Lab | Exercise 3a: Diffusion, Osmosis, & Diffusion Rate

The video tutorial by Kevin Tolkoff covers key concepts of cell transport, focusing on diffusion and osmosis. It explains kinetic energy, selectively permeable membranes, and the movement of solutes and water across membranes. The tutorial also discusses different solution types (hypotonic, isotonic, hypertonic) and factors affecting diffusion rates, such as molecular weight, surface area, temperature, and concentration gradients.

Explain the difference between isotonic, hypotonic, and hypertonic solutions.

Discuss the importance of understanding diffusion and osmosis in a laboratory setting.

What factors can increase the rate of diffusion?

How does temperature affect the rate of diffusion?
