Division of plant which includes ferns and fern allies is termed as pteridophytes. The various characteristics of pteridophytes are:
1) They reproduce by making spores. Unlike other plants, they do not produce seeds. Antheridia and archegonia are the male and the female organ respectively. Eggs in the archegonia are fertilized by the sperms produced by the antheridia to produce the zygote.
2) They grow in a wide range of habitats such as rock crevices, deserts, mountains and in moist and shady areas.
4) They have leaves, stem and roots but they do not have flowers. They have specialized leaves known as sporophylls which produce spores and have fibrous roots.
5) They are vascular plants i.e. they contain xylem and phloem which helps in the transportation of water and nutrients.
6) They have a complicate life cycle which includes alternation of generations. Their life cycle includes a haploid phase followed by diploid phase.

Pteridophyta are the first true land plants.
They are seedless vascular cryptogamae.
Spores develop in sporangia are homosporous or heterosporous.
Sporangia are produced in groups on sporophylls.
