• 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

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

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).
