Question

What is double fertilisation?

Answer 1

Double fertilisation

Double fertilisation, a characteristic feature of angiosperms, involves two fertilisation events as mentioned below:

• Syngamy: Fusion of one of the haploid male gametes released by the pollen tube with the haploid egg cell to form a diploid zygote.
• Triple fusion: Fusion of the other haploid male gamete with the diploid central cell to form the primary endosperm cell consisting of a triploid primary endosperm nucleus.
