3. Two or more seeds

🍌 Why Bananas Are Berries
Bananas qualify:
- ✅ Single ovary
- ✅ Three layers (peel, flesh, inner core)
- ✅ Multiple seeds (tiny black specks—vestigial in cultivated bananas)
Wild bananas: Have large, hard seeds (cultivated ones are seedless through selective breeding)

🍓 Why Strawberries Aren’t Berries
Strawberries are “aggregate accessory fruits”:
- Develop from multiple ovaries
- The “seeds” on the outside are actually individual fruits (achenes)
- The red flesh is swollen receptacle tissue (not from ovary)
Same with:
- Raspberries
- Blackberries
- Boysenberries
