This document summarizes the five kingdoms of life: plants, animals, bacteria, fungi, and protists. It describes some key characteristics of each kingdom. Plants are divided into vascular and nonvascular types. Animals are divided into vertebrates and invertebrates, with examples of vertebrate groups like mammals, reptiles, amphibians, fish, and birds. Bacteria are found in large numbers on human skin. Fungi can cause rust and mildew. Protists are single-celled organisms that live in aquatic environments like ponds and streams.
