Question

what is meant by"thallophytes,bryophytes &pteridophytes are very inconspicuous"?

Answer 1

Thallophyta, Bryophyta, and Pteridophyta are the three phyla of cryptogams, which is a subkingdom of Plantae. The cryptogams are seedless plants or plant-like organisms that do not produce flowers and fruits. They reproduce through the production of spores. Thallophyta, Bryophyta, and Pteridophyta differ by the organization of their plant body. The main difference between Thallophyta Bryophyta and Pteridophyta is that the plant body of Thallophyta is a thallus while the plant body of Bryophyta shows stem-like, root-like, and leaf-like structures and the plant body of Pteridophyta is differentiated into true stem, root, and leaves. Thallophyta and Bryophyta do not consist of a true vascular system while Pteridophyta consists of a true vascular system
