A diploid male angiospermic plant is crossed with tetraploid female plant. Endosperm of seed will be Correct Answer Pentaploid

A diploid male angiospermic plant is crossed with tetraploid female plant. Endosperm of seed will be Pentaploid.
The endosperm is a tissue produced inside the seeds of most flowering plants following the fertilization of male and female gametes. If 2n male is crossed with 4n female, then endosperm will be 5n as female gamete after meiosis form 2n gametes + n male gamete + 2n polar nuclei, therefore 5n ploidy for endosperm.
The endosperm plays an important role in supporting embryonic growth by supplying nutrients, protecting the embryo and controlling embryo growth by acting as a mechanical barrier during seed development and germination.
