When a cell divides, it needs a tiny set of organizing tools called centrosomes. Animal cells have them, and they help pull the chromosomes apart like tug-of-war ropes. It’s the cell’s choreographer for the mitosis dance.
Plant cells? They don’t have centrosomes. They just rely on other proteins to do the dance, because they’re too busy being square and making chlorophyll. It’s like one neighbor hires a wedding planner, and the other just does the Macarena spontaneously. And it works.
