The phylum Cycadophyta contains about 140 living species of plants called cycads, with more species present in the fossil record. Cycads have seeds and water-conducting vessels. Cycads belong to a larger group of plants called gymnosperms, which bear seeds in cone-like structures.
The plant kingdom is divided into different groups called phyla. One of these phyla is the anthophyta phylum. Anthophyta plants all have certain characteristics in common with one another. The anthophyta phylum is the largest division of photosynthetic organisms.
