Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Another one male gamete fertilises with two polar nuclei to form ____
A
diploid zygote
B
triploid nuclei
C
embryo
D
interguments
Explanation: 

Detailed explanation-1: -The other male gamete moves towards the two polar nuclei located in the central cell and fuses with them to produce a triploid primary endosperm nucleus. This completes the process of double fertilisation.

Detailed explanation-2: -When one male gamete fuses with an egg to form a zygote, it is termed as syngamy. The other male gamete fuses with the two polar nuclei, termed as triple fusion, which results in the formation of a triploid endosperm.

Detailed explanation-3: -double fertilization, in flowering plant reproduction, the fusion of the egg and sperm and the simultaneous fusion of a second sperm and two polar nuclei that ultimately results in the formation of the endosperm (the food-storage tissue) of the seed.

Detailed explanation-4: -3. The fusion of another male gamete with the secondary nucleus to form primary endosperm nucleus(PEN). Hence, the process is called triple fusion.

Detailed explanation-5: -Second male gamete fuses with two polar nuclei to form the primary endosperm nucleus.
