Double fertilization is characteristic of:
Correct answer: A. Angiosperms
- A. Angiosperms
- B. Anatropous
- C. Gymnosperms
- D. Bryophytes
Explanation
Double fertilisation is the characteristic feature of angiosperms. This phenomenon first observed by Nawaschin, 1898 in Lilium and Fritillaria. In angiosperms one male gamete fuses with the two polar nuclei to form triploid primary endosperm nucleus. The process is called triple fusion. These two acts together are known as double fertilisation.
