Question

The diploid and triploid product of double fertilization respectively are (1)Zygote and primary endosperm nucleus (2)Endosperm and cotyledons (3)Embryo and perisperm (4)Zygote and scutellum

Answer 1

Answer:

(1) Zygote and Primary endosperm nucleus

Explanation:

The zygote is formed by the fusion of the egg cell and one of the male gamete, both of which are haploid and therefore give a diploid product that is the zygote.

The primary endosperm nucleus is formed by the fusion of the other male gamete (haploid) and the polar nuclie (diploid) resulting into a triploid product.
