Question

Double fertilization is exhibited by :

• A. Gynmosperms
• B. Algae
• C. Fungi
• D. Angiosperms

Answer 1

The correct option is D Angiosperms

Double fertilization is a phenomenon which occurs in angiosperms (flowering plants).

Double fertilisation includes syngamy and triple fusion:
a. Syngamy - One of the haploid male gametes move towards the egg cell and fuses with its haploid nucleus resulting in the formation of a diplod zygote.

b. Triple fusion - The other haploid male gamete fuses with the two haploid polar nuclei located in the central cell of the embryo sac to produce a triploid primary endosperm nucleus (PEN).
