With more than 250,000 species, the angiosperm phylum (Anthophyta) is second only to insects in terms of diversification.

Four major adaptations are found in all terrestrial plants: the alternation of generations, a sporangium in which the spores are formed, a gametangium that produces haploid cells, and apical meristem tissue in roots and shoots.
