Which of the following is NOT a member of the Solanaceae (nightshade) family?

Your answer is correct. Pumpkin is indeed not a member of the Solanaceae family; it belongs to the Cucurbitaceae family instead. The Solanaceae, commonly known as the nightshade family, includes a variety of well-known plants such as bell peppers, eggplants, and tomatoes, all of which are characterized by their flowering properties and fruit types that can be termed berries. This family also includes many other species, some of which have medicinal or toxic properties.

The distinction is important if you're studying plant classifications and their nutritional implications, especially for individuals who may be sensitive to nightshades. Understanding these classifications can help in dietary planning and advising clients in a natural health context.
