Questions students ask

The real ones — pulled from the Q&A community and tutor sessions.

The potato is an underground stem called a tuber — it has buds (eyes) that can grow into new plants, which is a feature of stems, not roots.

Medicinal plants like tulasi, neem and amla contain natural compounds that help treat ailments — tulasi eases coughs, neem repels mosquitoes, and amla is rich in vitamin C with anticancer properties.
