Definition of Vegetables

The term "vegetable" can be somewhat ambiguous, as it encompasses a wide range of plant species. Generally, vegetables are defined as parts of plants that are consumed by humans or other animals as food. This includes leaves, stems, roots, tubers, bulbs, and flowers. In culinary terms, vegetables are often savory and used in main dishes or sides, unlike fruits, which are sweeter and typically consumed as snacks or desserts.

Botanical Classification of Onions

Botanically, onions (Allium cepa) are classified as bulbs. Bulbs are underground storage organs that allow plants to survive adverse conditions. They consist of layers of fleshy leaves, which store nutrients. Onions belong to the Allium family, which also includes garlic, chives, leeks, and shallots.

This classification places onions in a unique position because, while they are technically bulbs, they are often used in cooking as vegetables. Therefore, their classification can vary depending on the context.
