Detailed explanation-1: -The classification system groups, in order from largest to smallest, are kingdom, phylum or division, class, order, family, genus, and species (Figure 2). Linnaeus also described a bino-mial naming system. All organisms were given two names-the genus continues to evolve.

Detailed explanation-2: -Classification is the arrangement of organisms into groups (taxa, singular taxon) on the basis of their relationships. It follows that identification can take place only after a classification has been established.

Detailed explanation-3: -Plant systematics deals with interrelation between plants and their evolutionary descent. Systematics studies biological diversity and organises the information into a classification. Organisms are classified on the basis of similarities, closeness or relationship between them.

Detailed explanation-4: -What are the 4 main groups of plants? The four major groups are mosses, ferns, flowering plants, and gymnosperms.

Detailed explanation-5: -phenetic or numerical taxonomy; synthetic or traditional taxonomy; cladistic or phylogenetic taxonomy.
