Thallophyte
Thallophytes are a polyphyletic group of non-mobile organisms that are grouped together on the basis of similarity of characteristics, but do not share a common ancestor. They were formerly categorized as a sub-kingdom of kingdom Plantae. These include lichens, algae, fungus, bacteria and slime moulds.
Bryophyta
Bryophyta, the division of green plants, refers to embryophytes which in literal terms is land plants, especially the non-vascular onesThe only prime feature of a bryophyte is that it does not have true vascular tissue. Some do have specialized tissues which is used to transport water but are not considered to be a true vascular tissue due to the lack of lignin.Bryophytes are believed to evolve from charophytes and are considered to have been the first true plants ever evolved.
Pteridophyta
Before the flowering plants, the landscape was dominated with plants that looked like ferns for hundreds of millions of years. Today, their massive lineage have descendants that have almost the same characteristics as their ancient ancestors. Unlike most other members of the plant kingdom, pteridophytes don’t reproduce through seeds, they reproduce through spores instead.
PHANEROGAMS
The spermatophytes, also known as phanerogams or phenogamae, comprise those plants that produce seeds, hence the alternative name seed plants. They are a subset of the embryophytes or land plants.
ANGIOSPERM
The angiosperms, or flowering plants, are one of the major groups of extant seed plants and arguably the most diverse major extant plant group on the planet, with at least 260,000 living species classified in 453 families.They occupy every habitat on Earth except extreme environments such as the highest mountaintops, the regions immediately surrounding the poles, and the deepest oceans.
Gymnosperm, any vascular plants that reproduces by means of an exposed seed, or ovuke—unlike angiosperm, or flowering plants, whose seeds are enclosed by mature ovaries, or fruits. The seeds of many gymnosperms (literally “naked seeds”) are borne in cones and are not visible until maturit
