How Cellular Transport Works and Why Cells Are Small

Miacademy & MiaPrep Learning Channel

This comprehensive biology lesson breaks down the complex mechanisms of cellular transport, explaining how cells move materials across their membranes to survive. Using relatable analogies like room spray, messy bedrooms, and crowded malls, the video simplifies abstract concepts such as diffusion, concentration gradients, and the surface area-to-volume ratio. It visualizes microscopic processes, showing exactly how oxygen, carbon dioxide, glucose, and ions navigate the cell membrane boundaries.
