The phylum angiosperm (Greek meaning: covered seeds) contains the plants that we are most familiar with and includes all flowering plants which develop their seeds within a protective structure. Of all the species within the plant kingdom, about 380,000, the phylum angiosperm is the largest and most diverse phylum 64 orders, 416 families, about 13,000 genera and 300,000 known species.
The primary distinguishing feature of Angiosperms from other seed producing plants known as the Gymnosperm is that the Angiosperm plants all have flowers.
