The Spermatophyta or superior plants are the most widespread class of plants in the world. Their distinguishing feature is that for reproduction they have developed the reproductive organ par excellence, the flower, which originates the seed after fertilisation. The seed encloses the embryo of the plant, which consists of a tiny root and a shoot. Spermatophyta can be divided into Gymnospermae and Angiospermae. Gymnospermae have a naked seed, with no flower or fruit, and include conifers, ginkgoes and Cycadatae. Angiospermae have their seed coated and enclosed in a fruit.
