There is more to know about Angiosperms than what they are, like the characteristics they posses. You could know of some but here is an addition to what you know. They bear flowers which are reproductive structures. Fertilization takes place between male and female flower by pollination that includes insect pollination, wind pollination and animal pollination. Angiosperms have underground root as well as aerial shoot system. Angiosperms have very well-developed conducting tissues. These tissues include the xylem and the phloem arranged in form of vascular bundles. They have root that helps absorption of water and minerals from the soil. Most of them have leaves that carry out photosynthesis, so they are autotrophs. They have alternation of generation, Sporophyte generation alternate with gametophyte generation. The sporophyte is the dominant, diploid stage and is the more visible form of the plant, with the leaves, stems, roots, and flowers. Gametophyte generation is reduced and it is found within the ovary and anther.
