-Archaebacteria are single-celled organisms that can survive environments that are deadly to most other kinds of life. They live well in very hot,acid springs. Others can live in very salty water. These cells do not have a true nucleus. Archaebacteria

-Organisms in this kingdom are also single-celled. These organisms may have many different shapes. Some are spheres. Others look like rods. Some are even spirals. Some have structures like tails that wiggle and move them through water. These cells do not have a true nucleus. Eubacteria

-Most protists are single cells. Some, such as some algae,live in colonies. Protists such as algae are food for many animals. Some protists even live inside the digestive systems of certain animals,such as termites and cows,and help them digest plants they eat. These anmals would die without protists. Protista

-Fungi, such as mushrooms, are not plants because they are not able to make their own sugar for food. Mushrooms use hair-like structures to absorb and digest food from the materials they grow on. Yeast are single-celled fungi. Bakers use them in baking of bread. Yeast take in sugar from bread dough and release carbon dioxide. This gas gets trapped in the dough, causing the dough to rise. A yeast cell reproduces by dividing into two cells. Fungi

-Green plants have cell walls with cellulose and characteristically obtain most of their energy from sunlight via photosynthesis using chlorophyll contained in chloroplasts, which gives them their green color. Some plants are parasitic and may not produce normal amounts of chlorophyll or photosynthesize. Plants are also characterized by sexual reproduction, modular and indeterminate growth, and an alternation of generations, although asexual reproduction is common, and some plants bloom only once while others bear only one bloom.

-Animals are a major group of multicellular, eukaryotic organisms of the kingdom Animalia or Metazoa. Their body plan eventually becomes fixed as they develop, although some undergo a process of metamorphosis later on in their life. Most animals are motile, meaning they can move spontaneously and independently. All animals are also heterotrophs, meaning they must ingest other organisms or their products for sustenance. Most known animal phyla appeared in the fossil record as marine species during the Cambrian explosion, about 542 million years ago. Animal
