"Double fertilization" is a complex mechanism in flowering plants that is also unique to angiosperm. Choose the most appropriate statement from the option listed below that explains this phenomenon.

Options

A. Fertilization in two flowers of the same plant forming endosperms.
B. Two male gametes fertilize two eggs inside the ovule as a result the ovary gives rise to bigger fruits.
C. Two fertilizations occur in a flower-one fertilizatic results in the formation of a diploid zygote and the second fertilization results in the formation of triploid endosperm.
D. Two pollen grains sending two pollen tubes inside the ovary, resulting in the formation of two seed inside the fruit.

Answer

C

Explanation

In double fertilization one male gamete fuses with the egg and results in the formation of a diploid zygote and this process is called fertilization. The other male gamete fuses with the two polar nuclei to form a triploid endosperm. This process is called triple fusion. After fertilisation, the fertilized ovule forms the seed while the tissues of the ovary become the fruit.
