                                           Classification Of Plants



   Plants are classified according to their relationships. Species can be grouped by complexes,genera,families,orders,classes,phyla. And domains like Angiosperms ,Monocotyledons,Gymnoseperms,Ephedra Group and Equisetacease.They use to seperate groups by outward appearance.But now they seperate by looking their genetic relationships.

·        The firs person known to have tried to classify plants was Theophrastus.He organized the 500 plants into three main categories: tree,shrubs and herbs.Then plants were classified according to their leaf characteristics.


·        Many plants that are very closely related ,but have quite different leaves. Unrelated plants growing in similar environments will have similar leaves because these are adapted that help plants cope with shade or other stresses.
