Read the paragraph from a student’s report.

Fruits do not come from the same part of the plant as vegetables. Fruits come from any part of the plant that contains a seed. Some popular fruits are apples, strawberries, and bananas. If you look carefully, you’ll notice that each of these fruits has seeds. Fruits can usually be enjoyed without being cooked. Unlike fruits, vegetables do not have seeds. They come from other parts of a plant that can be eaten, such as the roots, stems, leaves, and flower buds. For example, lettuce comes from the leaf of a plant, while potatoes come from the root of a plant. Vegetables can be eaten raw, but many people prefer to eat them cooked.
