If an angiosperm male plant is diploid and female plant tetraploid, the ploidy level of endosperm will be:
Correct answer: D. Triploid
- A. Tetraploid
- B. Pentaploid
- C. Haploid
- D. Triploid
Explanation
If the female plant is tetraploid, then the central cell of the embryo sac, which is a fused polar nucleus, will also be tetraploid. Fusion of the tetraploid central cell to the haploid male gamete forms a pentaploid endosperm in the given example.
