Seedless vascular plants are classified into three phyla namely the club mosses, horsetails and ferns. Ferns form the numerous seedless plants with true vascular tissue, creeping underground stems called the rhizomes and large leaves called the fronds. They reproduce via spores.
Ferns crowd on the forest floors even after cutting them down. They invade the cleared zone of forest which has been cut for timber via numerous spores. The spores are in clusters called sori on the underside of the leaves. The spores develop into haploid gametophytes by mitosis. They also grow by spreading their rhizomes or from the tips of their fronds.
