Question

In the angiosperm ovule, central cell of the embryo sac, prior to the entry of pollen tube, contains

• A. A single haploid nucleus
• B. One diploid and one haploid nuclei
• C. Two haploid polar nuclei
• D. Two diploid secondary nuclei

Answer 1

The correct option is C Two haploid polar nuclei

• In the angiosperm ovule, the central cell of the embryo sac, prior to the entry of the pollen tube, contains two haploid polar nuclei.
• These two haploid polar nuclei will then fuse to form a secondary nucleus which is diploid in nature.
• The secondary nucleus will fuse with the male gamete to form primary endosperm nucleus (PEN) after entry of the pollen tube.

So, the correct answer is 'Two haploid polar nuclei'.
