In the angiosperm ovule, central cell of the embryo sac prior to the triple fusion, contains
- A single haploid nucleus
- One diploid nucleus
- One haploid polar nuclei
- One diploid and one haploid nuclei
The correct answer is: One haploid polar nuclei
In the angiosperm ovule, central cell of the embryo sac prior to the triple fusion, contains two haploid polar nuclei. Triple fusion in angiosperm is the fusion of second sperm with two polar nuclei or the secondary nucleus, which results in the formation of a triploid primary endosperm nucleus
