CLASSIFICATION OF LIVING ORGANISMS
• Classification: an orderly grouping of organisms according to selected criteria
• The study of classifying organisms is called taxonomy– Provides universal names for organisms– Provides a reference for identifying organisms

Plant Kingdom
Algae Mosses and Liverworts
Ferns Conifers Flowering plants
No roots, leaves, stemslive in waterform strings of cells
No true roots peel off easilyNo channels conducting plant nutrients (sap)
Have roots, stems and leavesHave channels for conducting plant
nutrients (sap)
No seeds Naked seeds in a cone
Seeds in a fruit
Reproduce by spores
Needle or scale leavesKeep them in winter
flowers

Two individuals belong to the same species if …
• They share similar characteristics,– for example physical resemblance
• They can reproduce (if of opposing sex), • The children of these two individuals are
viable (survive),• the children themselves can reproduce
successfully (they are fertile).
