In this article we will discuss about the classification of pteridophytes. The term Pteridophyta was first coined by Haeckel. Eichler (1883) divided the plant kingdom into Cryptogamia and Phanerogamia. The Cryptogamia was further divided into Thallophyta. Bryophyta and Pteridophyta. Engler (1909) included the Bryophyta and Pteridophyta under Embryophyta. Due to discovery of the fossil plants, the classification of Pteridophytes has [...]
In this article we will discuss about the similarities and difference between pteridophytes and bryophytes. Similarities between Pteridophytes and Bryophytes: (i) Both the groups have members with terrestrial mode of life. (ii) Like Bryophytes some Pteridophytes have rhizoids (e.g., Rhynia, Psilotum). (iii) Formation of spores is same in both the groups. Like Bryophytes many Pteridophytes are homosporous e.g., Equisetum, Rhynia, [...]
