NCERT REFERENCE

_When there are more than one, the pistils may be fused together (syncarpous)_

Gametogenesis refers to the process of formation of the two types of gametes_

In flowering plants, the unisexual male flower is staminate, i.e., bearing stamens, while the female is pistillate or bearing pistils._

When a fungus reproduces sexually, two haploid

hyphae of compatible mating types come together and

fuse. In some fungi the fusion of two haploid cells

immediately results in diploid cells (2n). However, in other

fungi (ascomycetes and basidiomycetes), an intervening

dikaryotic stage (n + n, i.e., two nuclei per cell) occurs;

such a condition is called a dikaryon and the phase is

called dikaryophase of fungus. Later, the parental nuclei

fuse and the cells become diploid.______________
