Types of plants : plant classification
Plants are the fundamental building blocks of life on earth. Plants
are life forms belonging to the kingdom Plantae. The
scientific study has revealed at least 500,000 species of plants. The
plants vary in size from microscopic algae, to huge sequoia
trees more than 8m (26 ft) tall.
Plant Kingdom is mainly classified into two . This type of plant classification
is done according to how they reproduce.
1) Spore bearing
plants ( Algae, mosses, ferns and their relatives)
2) Seed bearing
plants. (Conifers and flowering plants)
classification according to this criterion, can be pictorially
represented as follows:
The plant kingdom can also be classified on the basis
of the presence or absence of conductive (vascular) tissue.
Ferns (pteridophytes), gymnosperms and angiosperms have vascular tissue
which transports the nutrients and water through the plant. They are
collectively known as tracheophytes.
Mosses, liverworts, hornworts (bryophytes) are non-vascular
i.e. they do not have conductive tissue to transport sugar, water and
