Explanation:

Angiosperms are seed-bearing vascular plants. Their reproductive structures are flowers in which the ovules are enclosed in an ovary.
Angiosperms are found in almost every habitat from forests and grasslands to sea margins and deserts. Angiosperms display a huge variety of life forms including trees, herbs, submerged aquatics, bulbs and epiphytes.
The largest plant families are Orchids, and Compositae (daisies) and Legumes (beans).
The flowers of flowering plants are the most remarkable feature that distinguishes them from other seed plants.
Flowers initiated the differences between gymnosperms and angiosperms by broadening the scope of evolutionary relationships and niches open to flowering plants, allowing them to eventually dominate terrestrial ecosystems.
