Final answer:

Double fertilization is a characteristic of all angiosperms.

Step-by-step explanation:

One characteristic of all angiosperms is double fertilization. It is an event unique to angiosperms where one sperm fertilizes the egg and forms a diploid zygote, while the other combines with two polar nuclei and forms a triploid cell that develops into a food storage tissue called the endosperm.
