| Fungi Kingdom | |
| 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 material they grow on. Yeast are single-celled fungi. Bakers use them in the 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. |

| Diatom protist |
| Protist Kingdom | |
| 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 animals would die without the protists. |

| Eubacteria |
| Eubacteria Kingdom | |
| Organisms
in this kingdom are also single cells. 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. |

| Archaebacteria |
| Archaebacteria Kingdom | |
| 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. |
