Certain apomictic plants produce seeds without fertilization. How would the genetic makeup of the endosperm in such a plant likely differ from a sexually reproducing angiosperm?
It would be genetically identical to the maternal tissue.
It would be a mixture of maternal and paternal genes.
It would be entirely paternal in origin.
It would be haploid.
Which of the following statements BEST explains why double fertilization is advantageous for angiosperms?
It ensures the formation of a triploid endosperm, which is more resistant to pathogens.
It allows for the production of both seeds and fruits, enhancing dispersal.
It synchronizes endosperm development with embryo development, preventing wasted resources if fertilization fails.
It eliminates the need for separate male and female gametophytes.
