Answer 1

Double fertilisation is a very unique character of angiosperms

Answer 2

Angiosperm has double fertilization as one of the characteristics.

Explanation:  

Double fertilization involves the fusion of two sperm cells. In that one “fertilizes the egg cell” and hence to form the zygote, other egg fuses with the “two polar nuclei” to form the endosperm. This fertilization leads to the formation of fertilized ovules from the seeds and the tissue portion of the ovary forms the fruit. They are basically planted which produces flowers as well.
