The above division of 5 categories is done on basis of the development of plants..
Thallophyta shows minimal differentiation in plant organs n is mostly aquatic n are commonly called algae .for eg spirogyra.
Bryophyta are known as amphibians of plant kingdom.They grow along the water bodies n show some more differentiation .for eg mosses.
Pteridophyta have fully differentiated plant organs n have tissues for conducting food n water. for eg ferns n horsetails.
gymnosperms bear naked seeds on female cones.for eg pinus , deodar
Angiosperms refer to the plants that have flowers for reproduction n plant embryos are inside seeds with structure called cotyledons..basically referring to all the plants around us. for eg oranges,roses,apple, sunflower etc

These are all the classification of plant kingdom...
