Question:
What is triple fusion? Where and how does it take place? Name the nuclei involved in triple fusion.
Answer:
Triple fusion is a process of fusion of three haploid nuclei. It takes place in the embryo sac. The pollen tube containing two male gametes enters into the ovule through the micropyle. Among two gametes, one of the gametes joins with the egg cells that result in the production of zygote, whereas another gamete with two polar nuclei produces a triploid primary endosperm nucleus.
