How do scientists classify living things?The members of each group of living things share a setof special features unique to that group.For example, plants contain a chemical called_____________ that they use to make their own food(it also makes them ________ ). Every member of theplant kingdom shares this characteristic.Scientists are always looking for these characteristicsor observable features which allow them to groupdifferent species together and see how they arerelated to each other.
By comparing the features of different animals theyhave been able to classify them further, dividing eachof the kingdoms into smaller groups. Each kingdom isdivided into groups, and these groups are divided intosmaller groups. Each level of group has a specialname: King Puga Kingdom Came Over Phylum For Order Grits Class Sunday Family Genus Species
Kingdom MoneraType of organism: BacteriaNumbers of species: We cannot begin to estimateWhere they are found: Everywhere - all imaginablehabitatsDescription: Bacteria are single celled organisms. They canbe rod shaped, spiral shaped or round, with hairs (cilia) ortails (flagella) that let them move around. They reproduceby dividing - populations of bacteria can grow very quickly.Need to know: Bacteria can live everywhere - deep in theocean in complete darkness, in acid pools, in alkali lakesand even deep within the Earths crust where no other lifeexists.
Kingdom Fungi Type of organism: Fungi including mushrooms, toadstools and yeasts Numbers of species: About 70,000Where they are found: Almost everywhere - in the sea, infreshwater, and on landDescription: Fungi can be single celled organisms like yeasts, ormulticellular (many celled), like toadstools mushrooms andmoulds. Although they often look like plants, fungi do not producetheir own food as plants do. Instead they live off dead or decayingplant or animal material.Need to know: Fungi can be very useful - penicillin is made frommoulds, yeast is used in baking and brewing, and we eatmushrooms on toast for breakfast!
Kingdom AnimaliaType of organism: All animals, including you!Numbers of species: 1,500,000 - but this is only a rough guessWhere they are found: Almost everywhere - in the sea, infreshwater, and on landDescription: Animals are multicellular (____________celled)organisms. Their cells have no cell walls, and they do not producetheir own food (as plants do).Need to know: There are many different groups of animals, allliving in different ways. Sponges, corals, worms, insects, crabs,snails, starfish, birds, mammals, reptiles, fish and amphibians areall animals. Explore Animal I.D. a bit more to find out how weclassify animals.
Kingdom Plantae Type of organism: All plants, except for the simplest single-celled algaeNumbers of species: Around 400,000Where they are found: Almost everywhere - in the sea, infreshwater, and on landDescription: Plants are multicellular organisms. Their cells usuallyhave thick cell walls, and they all have a pigment called______________________ that they use to produce their ownfood in a process called ___________________.Need to know: There are many different groups of plants. Algae(like seaweed), mosses, ferns, pine trees, and flowering plants aredifferent groups of plants, with different ways of living andreproducing.
Kingdom ProtoctistaType of organism: Protists including single celled algae,slime molds and amoebaNumbers of species: Tens of thousands - but probablymany moreWhere they are found: Almost everywhere - in the sea,in freshwater, and on landDescription: Protists are single celled organisms, andlike animal and plant cells they have a nucleus. Thereare many different types of protists - some that act likeplants and make their own food, and some that aremore like animal or fungal cells.Need to know: Some protists cause disease. Oneprotist, called Plasmodium, causes Malaria - a diseasethat causes thousands of deaths each year.
