Pteridophytes: Cryptogams – Non-flowering and non-seed bearing

Cryptogams – Non-flowering and non-seed bearing plants. E.g. Thallophyta, Bryophyta, Pteridophyta Phanerogams – Flowering and seed-bearing plants. E.g. Gymnosperms, Angiosperms Also Read: Difference Between Bryophytes and Pteridophytes To learn more about plant kingdom Class 11, its characteristics and classification, explore BYJU’S biology. Before the flowering plants, the landscape was dominated with plants that looked like ferns for hundreds of millions of years. Pteridophytes show many characteristics of their ancestors. Unlike most other members of the Plant Kingdom, pteridophytes don’t reproduce through seeds, they reproduce through spores instead. Pteridophyta Classification Pteridophyta is classified into four main classes: Psilopsida They are the most primitive. The stem is photosynthetic and dichotomously branched ... The plant kingdom is very vast with a number of classifications. A plant can be classified into Thallophyta, Bryophyta, Pteridophyta. They are differentiated on the basis of the structure, presence or absence of transport tissues, and the ability to bear seeds. The Important Questions for Class 11 Biology Plant Kingdom are given below. These will provide a better understanding of the concepts. Pteridophytes are the first true land plants. They do not reproduce through seeds, instead, they reproduce through spores. Furthermore, Pteridophytes can be classified into Lycopodiopsida and Polypodiopsida. They are seedless, vascular cryptogams and show true alternation of generations.
