HORTICULTURE

Detailed explanation-1: -Angiosperms are classified in a single phylum: the Anthophyta. Modern angiosperms appear to be a monophyletic group, which means that they originated from a single ancestor. Flowering plants are divided into two major groups according to the structure of the cotyledons and pollen grains, among others.

Detailed explanation-2: -Angiosperms are plants that produce flowers and fruit. Angiosperms can be self-pollinated, meaning pollen falls on the stigma of the same flower, or cross-fertilized, during which pollen from one flower travels to a stigma of a flower on another plant.

Detailed explanation-3: -The success of angiosperms is due to two novel reproductive structures: flowers and fruit. The function of the flower is to ensure pollination. Flowers also provide protection for the ovule and developing embryo inside a receptacle. The function of the fruit is seed dispersal.
