FC: Classification of Living Things: Domains, Kingdoms and Vertebrate Groups By Pascale Bronder | 2010

1: Domains | Domains are a relatively new classification in which the kind of cell a living organism has determines what Domain it's in. There are three Domains and everything living falls into one of them.

2: Archaea | Archaea is one of the three Domains. All of the organisms that fall into this classification are one-celled organisms.They are very similar to bacteria, yet they are genetically very different. "Archaea" is Greek for "ancient" and organisms in this Domain live in environments that are similar to what Earth was like long ago.

3: Bacteria | These are one-celled organisms. They are also prokaryote cells. This means that they are cells with no nucleus. | A bacteria cell

4: Eukarya | Every organism in this Domain have eukaryote cells. That means they are cells with a nucleus. This Domain also includes almost all of Earth's multi-cellular organisms, but Eukarya also includes some unicellular organisms.

5: Kingdoms | Kingdoms are a slightly more specific classification than Domains. There are five Kingdoms and each living organism is classified by the characteristics of the cells that they contain.

6: Monera | These organisms are made of prokaryote cells. They get the nutrients they need when they pass through their cell membrane. They reproduce by dividing in two. Many bacteria are members of this Kingdom.

7: Protista | Protists are usually unicellular organisms, but they can be multi-cellular. They consist of eukaryote cells. They reproduce by splitting in two. Some get their nutrients by eating other organisms, others make food from the sun (photosynthesis).

8: Fungi | Most of the organisms are multi-cellular, but there are some one-celled organisms. They reproduce by spored and get their nutrients by absorbing the surface they live on. There are about 75,000 identified species of Fungi. | Various mushrooms

9: Plantea | All of these living organisms have many cells which are eukaryote cells. They get their energy from the sun, and their nutrients from their surroundings (like soil). Many reproduce by seeds. | There are about 375,000 different species of plants. | Leaves | Bushes | Trees | Flowers

10: Animalia | Insects are the most populated species in the Animal kingdom. There are 950,000 species of insects. | There are 1,250,000 identified different species of animals. | Organisms that belong to this Kingdom are all multi-cellular and all are eukaryote cells. They reproduce by cells that grow in the mother's body. They get their energy and nutrients by eating other organisms. | Insects

11: When people think of animals, they think of the domestic animals that many of us are familiar with. Not many people know that there are only 5,416 mammals out of 1,250,000 animals. | Lion | Puppies | Kittens | Horse

12: Vertebrates are animals with backbones. There are five major vertebrate groups: Mammals, Birds, Fish, Reptiles, and Amphibians.

13: Mammals | Almost all mammals give birth to live young and nurse with milk. They all have hair or fur and are warm blooded.

14: Mammals Monotremes | Monotremes lay eggs. They are also the oldest Order still in existence. | Duck-billed Platypus | Echidnas

15: Marsupials have a pouch to carry their young in. They are a primitive group of mammals and evolved before placental mammals. | Mammals Marsupials | Kangaroo | Wombat | Opossum

16: Mammals Placental Mammals | Polar Bear | Tiger | These are mammals in which the fetus is attached to the wall of the uterus and nourished through a spongy material (the placenta). Humans are a part of this group.

17: Birds | Birds are warm-blooded mammals that lay fragile eggs. They also have feathers on their skin and breath with their lungs. Although all birds have wings, not all bids can fly. | Penguins | Peacock | Various Birds | Cardinal | Penguins are among the species of birds that can't fly.

18: Fish | Various Fish | Fish are cold-blooded animals that are usually covered in scales. They live in water and most use gills, not lungs, to breath. | Goldfish

19: Reptiles | Reptiles are cold-blooded vertebrates, usually with scaled or horny plates on their skin. They breath through lungs and lay leathery eggs on land. | Corn Snake | Tortoise | Turtle

20: Salamander | Frog | Amphibians are also cold-blooded animals. Their skin is moist with no scales and they lay soft, jelly-like eggs in the water. | The young go through stages from tadpole to adult. Young ones breath with gills, adults usually breath with lungs, but some can breath through their skin. | Toads are also part of this group.
