Angiosperms may be monoecious or dioecious and undergo sexual reproduction. Outline the components of a flower and their function. A typical flower has four main parts, or whorls: the calyx (sepals), corolla (petals), androecium (male reproductive structure), and gynoecium (female reproductive structure).
As in gymnosperms, the male gametophyte is the pollen grain. In order for fertilization to occur in most flowering plants, insects or other animals must transport the pollen to the pistil. A major distinguishing feature of angiosperms is the practice of double fertilization. An angiosperm ovule contains an egg cell and a diploid fusion nucleus, which is created through the joining of two polar nuclei within the ovule.
