what is Thallopyhyta,bryophyta and pteridophyta?​best answer will mark as brainleliest⚡

Answer 1

Thallophyta Bryophyta Pteridophyta

Plant body is thallus. It is not differentiated into root, stem and leaves. Plant body does not have true roots, stems and leaves but shows root like and leaf-like structures. Plants have true roots, stems and leaves.

There is no vascular system (i.e., conducting tissue which can transport water, minerals and food. True vascular system is absent. True vascular system is present.

Sex organs are unicellular. Sex organs are multicellular. Sex organs are multicellular.

No embryo formation takes place after fertilization. Embryo is formed after fertilization. Embryo is formed after fertilization.

Example: Algae. Example: Mosses. Example: Ferns.

$\huge \mathfrak \blue { \underline {Thallophyta}}$

Thallophytes (Thallophyta or Thallobionta) are a polyphyletic group of non-motile organisms traditionally described as "thalloid plants", "relatively simple plants" or "lower plants". They form an abandoned division of kingdom Plantae that include fungi, lichens and algae and occasionally bryophytes, bacteria and slime moulds. Thallophytes have a hidden reproductive system and hence they are also incorporated into the similarly abandoned Cryptogamae (together with ferns), as opposed to Phanerogamae.

$\huge \mathfrak \blue { \underline {Bryophyta}}$

It is a division of nonflowering plants comprising the mosses and liverworts characterized by rhizoids rather than true roots, by little or no organized vascular tissue, by multicellular archegonia and antheridia in which only some of the cells are sporogenous, and by a clear-cut alternation of generations, the sporophyte being without chlorophyll and remaining attached to and nourished by the gametophyte.

$\huge \mathfrak \blue { \underline {Pteridophyta}}$

A pteridophyte is a vascular plant (with xylem and phloem) that disperses spores. Because pteridophytes produce neither flowers nor seeds, they are sometimes referred to as "cryptogams", meaning that their means of reproduction is hidden. Ferns, horsetails (often treated as ferns), and lycophytes (clubmosses, spikemosses, and quillworts) are all pteridophytes.
