Plants are organized into four main categories, based upon their phylum, tissue structure, seed type and stature. Animals classification 1. The respective roles of cytology and genetics in plant classification and the relation between phylogeny and taxonomy are among the topics discussed. The gradual recognition that the structure of the flower is of more fundamental importance in classification than are vegetative characters opened the gate for the “sexual system” of Linnaeus classification.

First logical and elaborate classification in the written from was done by Aristotle (384 – 322 B.C) and his pupil Theophrastus (372 – 287 B.C). Carl Linnaeus grouped plants according to the number of stamens and carpels, their union and their presence and absence in the flower. Whereas understand of interrelationship of plants forced him to classify and arrange them so as to manipulate the plants and plant products for his utilization in more befitting manner. The five-kingdom proposed consist of: Kingdom Prokaryotes (Monera, or bacteria) These are prokaryotic unicellular organisms. Every classification was based on phylogeny and thus the plants were arranged in an ascending series from the most primitive to the most complex one. grasses: plants that have slender leaves and reproduce by sending out underground stems called rhizomes that usually grow horizontally.

Addition of data and especially the invention of instruments and support provided by biochemistry jolted the very basis of classification. Plant anatomy or phytotomy is the general term for the study of the internal structure of plants.Originally it included plant morphology, the description of the physical form and external structure of plants, but since the mid-20th century plant anatomy has been considered a separate field referring only to internal plant structure.

Whittaker classification of plants and other organisms were based on five kingdoms which owe’s a great debt to the four-kingdom system of Herbert F. Copeland from Sacramento City College, California, published in 1956 mentioned below: Briefly the five-kingdom system is based on the three different levels of cellular organization associated with three principals’ modes of nutrition photosynthesis, absorption and ingestion. They have a different cell structure , but most of them come under two basic shapes like bacillus or cocci. They based their classification on apparent size of the plants visible by naked eye only. The gametophyte is highly developed and differentiated than that of complex algae. (iv) The zygote never develops into a multicellular embryo while still within the female sex organ.
