by looking for seed coats on the seeds by looking for wing-like structures on the seeds by looking for fruit tissue around the seeds by looking for young sporophytes inside the seeds
I gave my students this multiple choice question: During a walk in the woods, Mandy finds a plant structure that had fallen onto the trail. Mandy can tell the object contained seeds, and thinks it came from a flowering plant instead of a conifer. How can she determine if the object came from a flowering plant?

Only one answer is correct among these 4 choices:
- by looking for seed coats on the seeds
- by looking for wing-like structures on the seeds
- by looking for fruit tissue around the seeds
- by looking for young sporophytes inside the seeds

Could you tell me which one is correct?
