Pollen grains with generative and tube nuclei have two haploid nuclei.
No. Haploid cells/nuclei can only be created in meiosis.
Polar nuclei are typically haploid. In the context of plant reproduction, specifically within the embryo sac of angiosperms, polar nuclei are formed from the fusion of two haploid nuclei. These nuclei eventually contribute to the formation of the triploid endosperm when fertilization occurs.
Formation of 4 haploid nuclei
The dikaryotic stage in a fungus life cycle is characterized by cells containing two genetically distinct nuclei that are not yet fused. This stage follows the fusion of haploid nuclei from two mating strains but precedes the formation of diploid nuclei through nuclear fusion. Dikaryotic cells are essential for the development of fruiting bodies and sexual reproduction in fungi.

Ascus is the structure that contains two haploid nuclei in fungi, particularly in the Ascomycota division. These nuclei are produced by the fusion of two haploid nuclei during sexual reproduction and can undergo meiosis to produce spores.
Plasmogamy is the fusion of cytoplasm from two haploid fungal cells, resulting in the formation of a dikaryotic cell with two separate haploid nuclei. Karyogamy is the fusion of the two haploid nuclei within the dikaryotic cell, leading to the formation of a diploid nucleus, which eventually undergoes meiosis to produce haploid spores.
formation of four haploid nuclei.

The ovule largely consists of diploid cells except in its embrosac where egg apparatus, polar nuclei and antipodal cells are haploid.
I am sure it is (3n).This is because In angiosperms most common type of embryo sac formation, there is fusion of 1 sperm nuclei + 2 polar nuclei=triple fusion resulting in a triploid primary endosperm nuclues.

Formation of four haploid nuclei. ignore nova net = scam
in meiosis, two new haploid sex cells are "born" by the division of two other haploid sex cells. So, at the end, there are 4 nuclei.
