Passive Transport: Osmosis in Animal and Plant Cells
Osmosis is the movement of water across a semipermeable membrane from a region of lower solute concentration to higher concentration. Tonicity refers to how an extracellular solution affects a cell’s water content, described as...

Passive Transport: Diffusion, Facilitated Diffusion & Osmosis
Passive transport includes diffusion, facilitated diffusion, and osmosis, all of which move substances down their concentration gradients without energy input. Small, uncharged molecules like oxygen and carbon dioxide diffuse freely,...

Basics of Osmosis
In this video, we explore the basics of osmosis, solute-driven water movement. We also discuss the meaning of hypotonic, hypertonic, and isotonic solutions.
