Basics of Osmosis

The video explains osmosis as the movement of water from low to high solute concentration to achieve equilibrium. It covers isotonic, hypertonic, and hypotonic solutions, detailing their effects on cells. In hypertonic solutions, cells shrink (crenation), while in hypotonic solutions, they swell and may burst (lysis). The importance of maintaining isotonic conditions is emphasized, with a real-world example of why drinking seawater is harmful.
