Pteridophyta belongs to the sub-kingdom Cryptogamae. This sub-kingdom includes plants which do not flower in their life time. Plant body is not well differentiated into stem, leaves etc. Reproductive organs are hidden. These are less evolved plants. These plants do not bear seeds. These can reproduce through spores. e.g. Ferns are primitive plants belonging to Division Pteridophyta.These are adapted to live on dry land. These possess compound leaves and reproduce by spores.Phanerogamae: This sub-kingdom includes plants which flower to perform sexual reproduction. Plant body possess well-formed stem, leaves and roots. These plants produce seeds. Seeds germinate into new plants. Phanerogams are further classified into Gymnosperms and Angiosperms.
