A plant grows mainly in water and has a body that is not differentiated into true roots, stems, and leaves. To which group does it belong?
Thallophyta
Thallophyta are plants whose body is not differentiated into true roots, stem and leaves; the undifferentiated body is called a thallus. They are predominantly aquatic, and common examples are algae such as Spirogyra, Ulothrix and Chara.
Bryophyta (mosses, liverworts) are amphibians of the plant kingdom; their body is differentiated into stem-like and leaf-like structures and they live mainly on moist land, not in water.
Pteridophyta (ferns) and gymnosperms have a body clearly differentiated into true roots, stem and leaves with vascular tissues, so they do not fit the description.
Hence, Thallophyta.
