Understanding the Real Difference — and Why It Matters
When you stroll through a greengrocer’s stall or browse a supermarket aisle, it’s easy to assume you know your fruits from your vegetables. Apples? Fruit. Carrots? Vegetable. Tomatoes? Surely a vegetable… right?
Well, not quite.
Botanical Definitions: It’s All About the Plant
In the world of botany, plants are classified based on their structure and function. Here’s how the definitions break down:
- Fruit (botanically): A fruit is the mature ovary of a flowering plant, typically containing seeds. It develops from the flower of the plant and is often used to spread seeds and ensure reproduction.
- Vegetable (botanically): This term refers to any other edible part of the plant — such as roots, stems, leaves, bulbs, or even flower buds.
So, by this strict botanical definition, many foods we casually call “vegetables” are actually fruits — including tomatoes, cucumbers, courgettes (zucchini), aubergines (eggplants), and peppers.
Culinary Definitions: Flavour Over Function
In the kitchen, we categorise produce based on taste and use rather than plant anatomy:
- Fruits (culinary): Usually sweet or tart, served in desserts, eaten raw, or juiced (e.g., apples, berries, oranges).
- Vegetables (culinary): Generally savoury or earthy, used in salads, soups, mains, or stews (e.g., carrots, spinach, potatoes).
This is where the confusion starts — and it’s why tomatoes, while botanically fruits, are almost universally treated as vegetables in cuisine.
🍅 Tomato: The Most Misunderstood Fruit
The humble tomato is probably the most notoriously mislabelled fruit in the world.
Botanically
Tomatoes develop from the flower of the tomato plant and contain seeds, making them fruits — just like apples or melons.
Culturally and Culinarily
Due to their savoury flavour and culinary use, tomatoes are almost always considered vegetables.
A Tomato Went to Court?!
Yes! In 1893, the United States Supreme Court ruled that tomatoes should be taxed as vegetables under customs law (Nix v. Hedden), despite their botanical identity. The court acknowledged that tomatoes are botanically fruits, but sided with their culinary use as vegetables.
This ruling only added to the global confusion!

- Onion – bulb
- Lettuce – leaf
- Beetroot – root
- Cauliflower – flower buds
- Leek – stem and leaf
Why This Matters
Understanding the real difference helps in:
- Agriculture & trade classifications
- Dietary planning and nutrition labelling
- Education & food science
- Even legal and customs purposes, as seen in the tomato case!
It also reminds us how language, culture, and science don’t always align — and that food is as much about context as it is about chemistry.
Quick Recap
- Fruit (botanical): Comes from flower, contains seeds (e.g., tomato, pepper, cucumber)
- Vegetable (botanical): All other edible parts of the plant (e.g., carrot, broccoli, spinach)
- Culinary practice: Depends on taste and how it’s used — not on plant biology
- Tomato: A fruit by science, a vegetable by use
