DENDROLOGY

Detailed explanation-1: -Angiosperms are easily classified because of the that they produce. An angiosperm having one cotyledon and parallel veins in their leaves. An angiosperm having two cotyledons and leaves with branching veins. A flower-producing vascular plant in which the seed is enclosed in a fruit.

Detailed explanation-2: -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-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.

Detailed explanation-4: -Angiosperms are classified into dicots and monocots. This classification is done on the basis of the number of cotyledons in the seed.
