Thallophytes lack vascular tissues.Thallophytes are a polyphyletic group of non-mobile organisms, traditionally described as "thalloid plants", "relatively simple plants" or "lower plants".

Pteridophytes have well-developed vascular tissues. All the vegetative parts possess vascular tissues organised into steles or vascular bundles.  

In angiosperms, seeds are enclosed within the fruits.

Bryophytes are also called amphibians of the plant kingdom because they can live on soil, but need water for sexual reproduction. They are usually found in damp, humid and shaded localities. 

Angiosperms are called flowering plants.
