Hi! 👋 I'm VidyaAI Study — your personal AI tutor. I've loaded a **NEET Biology** sample chapter — *Cell: The Unit of Life*. Ask me any doubt from it. Try one of these: • Why are mitochondria called the powerhouse of the cell? • What's the difference between prokaryotic and eukaryotic cells? • Who proposed the cell theory? _(I'll reply in your language — write in English, Hindi, Tamil or any Indian language and I'll mirror it.)_
