Which item is a simple fruit formed from one ovary?

• A. Walnuts
• B. Tomatoes
• C. Strawberries
• D. Peanuts

Answer: (B)

A simple fruit forms from one ovary of a single flower. A tomato fits this idea because it develops from the ovary of one flower, and the fleshy tissue you eat comes from that ovary’s wall, classifying it as a simple fruit—specifically a berry. Strawberries don’t fit because the red part is mostly the enlarged receptacle, while the actual fruits are tiny seeds on the surface, each from separate ovaries, making it an aggregate fruit. Peanuts aren’t either since they are seeds inside a pod, with the pod representing the legume fruit, not a single fleshy fruit from one ovary. Walnuts are dry nuts with a hard shell and don’t match the single-ovary, fleshy-fruit pattern in the same straightforward way. So the tomato is the clear example of a simple fruit formed from one ovary.
