🔤 Biology Quiz

Biology Quiz is a free online quiz on ArcadeOwl built around living things, cells and the natural world. Each round fires a fresh mix of multiple-choice questions — think what carries genetic information, how plants make food and the largest organ of the body — and a ticking timer that rewards you for answering fast and sure. String correct answers together and your streak multiplier sends the score soaring, while a quick fact after every question means you walk away a little smarter than you arrived. What makes Biology Quiz so replayable is the way questions are shuffled every single time, so two rounds are never quite the same and there is always a tougher fact waiting to catch you out. It is a brilliant warm-up before a pub quiz, a quick break between tasks, or a friendly head-to-head to settle who really knows living things, cells and the natural world. It runs entirely in your browser with full touch and keyboard support, so it plays just as smoothly on a phone as on a desktop — no download, no sign-up, and your personal best is saved automatically for next time. If you enjoy living things, cells and the natural world, Biology Quiz is an easy one to come back to again and again.
