Question

The diploid and triploid product of double fertilization respectively are:

• A. Zygote and primary endosperm nucleus
• B. Endosperm and cotyledons
• C. Embryo and perisperm
• D. Zygote and scutellum

Answer 1

The correct option is A Zygote and primary endosperm nucleus

Double fertilization includes two different fertilization events happening and is characteristic of angiosperms. The first fertilization event is the fusion of the haploid male gamete with the haploid egg cell forming a diploid zygote.
The second fertilization event is the fusion of the second haploid male gamete with a diploid secondary nucleus forming a triploid primary endosperm nucleus.
