Classification among plants depends on
whether the plant body has well differentiated, distinct components,
whether the differentiated plant body has special tissues for the transport of water and other substances within it,
ability to bear seeds, and
whether the seeds are enclosed within fruits.
Phylogenetic classification [evolutionary relationships], cytotaxonomy [cytological information like chromosome number, structure, behavior] and chemotaxonomy [chemical constituents of the plant], are used by taxonomists for classifying plants.
Plants are multicellular eukaryotes with cell walls mainly made of cellulose {Plant Cell vs. Animal Cell}.
They are autotrophs and use chlorophyll for photosynthesis. A few members are partially heterotrophic such as the insectivorous plants or parasites. Bladderwort and Venus fly trap are examples of insectivorous plants and Cuscuta is a parasite.
Plantae includes algae, bryophytes, pteridophytes, gymnosperms and angiosperms.
Fungi, and members of the Monera and Protista having cell walls have now been excluded from Plantae. So, the cyanobacteria that are also referred to as blue green algae are not ‘algae’ any more.
