The animal kingdom is the largest kingdom with over 1 million known species. All animals consist of many complex cells. They are also heterotrophs.
It contains all the plants that you have come to know - flowering plants, mosses, and ferns. Plants are all multicellular and consist of complex cells.
With over 250,000 species, the plant kingdom is the second largest kingdom. In addition plants are autotrophs, organisms that make their own food
Mushrooms, mold and mildew are all examples of organisms in the kingdom fungi. Most fungi are multicellular and consists of many complex cells.
Unlike plants, fungi cannot make their own food. Most obtain their food from parts of plants that are decaying in the soil. Some fungi taste great and others can kill you!
Like archaebacteria, eubacteria are complex and single celled. Most bacteria are in the EUBACTERIA kingdom. They are the kinds found everywhere and are the ones people are most familiar with. Most eubacteria are helpful. Some produce vitamins and foods like yogurt. Others cause diseases.
In 1983, scientists tool samples from a spot deep in the Pacific Ocean where hot gases and molten rock boiled into the ocean form the Earth’s interior. To their surprise they discovered unicellular (one cell) organisms in the samples. These organisms are today classified in the kingdom, Archaebacteria.
Archaebacteria are found in extreme environments such as hot boiling water and thermal vents under conditions with no oxygen or highly acid environments.
Slime molds and algae are protists. Sometimes they are called the odds and ends kingdom because its members are so different from one another. Protists include all microscopic organisms that are not bacteria, not animals, not plants and not fungi.
Most protists are unicellular and, unlike bacteria, protists are complex cells.
