Potato, ginger, onion and carrot are all 'underground vegetables' — are they the same kind of organ?
No — they're different modified organs.
No — they're different modified organs. Potato is a stem tuber and ginger is a rhizome (both stems with nodes and buds). Onion is a bulb — a compressed stem with fleshy storage leaves. Carrot is a true tap ROOT swollen with food. So three of them are modified stems or leaves and only the carrot is a root, even though all store food underground.
Key point
Potato/ginger = modified stems, onion = modified leaves (bulb), carrot = modified root.
Common mistake
lumping all storage organs together as 'roots'.
Memory tip
look for nodes/buds: present → stem (potato, ginger); absent → root (carrot).
