Question

Where does triple fusion take place in a flowering plant? Why is it so called? Mention its significance.​

Answer 1

Explanation:

✔ Triple fusion takes place inside the embryo sac.

✔ The pollen tube releases two male gametes into the embryo sac. Out of the two male gametes, one gamete fuses with the nucleus of the egg cell and forms the diploid zygote (syngamy).

✔The other male gamete fuses with two polar nuclei and results in the formation of triploid primary endosperm nucleus. Since this process involves the fusion of three haploid nuclei, it is known as triple fusion.

✔ Triple fusion is significant as it results in the formation of endosperm. Endosperm is a nutritive tissue that surrounds the embryo and provides nutrition in the form of starch, though it can also contain oils and protein.

Answer 2

TRIPLE FUSION ......

It takes place in the embryo sac in the angiosperms (also called flowering plants). It is known as triple fusionbecause it involves the fusion of two polar nuclei with one sperm nucleus, that results in the formation of endosperm...
