Centrosome & Centriole | Cell the unit of life | Grade 11 | Biology | Khan Academy

Ever wondered how your cells know EXACTLY where to split during division without making a mess of your DNA? The secret lies in a tiny cellular command center called the centrosome! This microscopic organelle acts like a GPS for cell division, organizing the spindle fibers that grab onto chromosomes and pull them to opposite ends of the cell with perfect precision. Without these cartwheel-shaped structures working behind the scenes, your cells would be in chaos - DNA scattered everywhere, division going wrong, and life as we know it impossible. Discover how these organelles ensure every cell division is a masterpiece of biological engineering! 00:00 - Introduction 00:58 - What is a cetrosome? 01:32 - Centrioles 03:08 - Cross-section of a centriole 04:10 - What happens to the centriole during cell division?
