Which of the following features differentiate angiosperms from gymnosperms?
Correct answer: C. Ovaries
- A. Pollens disperse by air
- B. Haploid microspores
- C. Ovaries
- D. Pollen tubes
Explanation
Angiosperms have ovaries, which are structures that enclose and protect the seeds. Ovaries are part of the flower and develop into fruits after fertilization. Gymnosperms lack true ovaries. Instead, the seeds are exposed on the surface of cone scales. Gymnosperms include conifers, cycads, ginkgos, and gnetophytes.
