Explanation

Double fertilization in angiosperms involves one sperm fertilizing the egg (forming zygote) and another fertilizing the two polar nuclei (forming triploid endosperm). The endosperm serves as nutritive tissue for the developing embryo. Cotyledon is part of embryo, and nucellus is part of ovule.
