Answer:
Thallophyta- Includes all algae e.g. Chlamydomonas, volvox, etc. Thallophytes are autotrophic as they contain chlorophyll. They have a thallus-like body, ie. the plant body can not be distinguished into roots stems or leaves . They are primarily aquatic.
Bryophyta- e.g. mosses and liverworts plants belonging to this group have a plant body that has false root-like structures called rhizoids, and leaf-like structures. They are autotrophic.
Pteridophyta- Includes all ferns. Plants belonging to this group have a plant body that can be distinguished into roots, stems, and leaves. The leaves are often made of leaflets bearing spores on the underside . They are non-flowering plants.
Gymnosperm-e.g. cycads,pine,fir etc . The plants belonging to this group bear naked seeds that are not enclosed on fruits They bear both male and female flowers. They are of two types cycads and conifers.
Angiosperm-Includes all flowering plants. Plants belonging to this group have a highly developed plant body, which can be differentiated into root, stem, leaves, flowers, and fruits. The seeds are enclosed in a fruit. They are further divided into monocots and dicots.
