Like all plants, angiosperms have an alternation of generations. What structure is a gametophyte in the angiosperm life cycle?

The structure is haploid gametophyte (male and female gametophyte)

Explanation:

Angiosperm is a seed-producing plant that is able to produce male and female gametophyte and with this they are able to carry out double fertilization. The pollen grains are formed by microspores (male gametophytes) and the ovule are formed by the megaspores (female gametophytes).
