Question

Thallopyhta and petridopyhta difference

Answer 1

Answer:

Thallophyta:-

Thallophyta is a group of non-motile organisms that are nonvascular primitive or lower plants. They possess a thallus-like undifferentiated plant body. Hence, they do not have true leaves, stem, and roots.

This group includes mainly fungi, lichens, and algae. They are mostly found in both freshwater and marine water environments. These plants also show alternation of generation. Furthermore, their sex organs are unicellular.

Pteriodophtes:-

Pteridophytes are the first true land plants. They are a group of vascular plants that are seedless. They reproduce via spores. Furthermore, they possess differentiated and erect plant bodies that have true leaves, true stem, and true roots. Ferns, horsetails, and lycophytes are the three major groups of pteridophytes. Lycophytes include club mosses, quillworts and spike mosses.

In addition, pteridophytes show alternation of generations. Their sporophytic generation is dominant over the gametophytic generation. Moreover, one of the prominent characteristics of pteridophytes is circinate vernation. Young leaves of pteridophytes show circinate vernation. Sex organs of the pteridophytes are multicellular, unlike thallophytes.
