Classifying Living Things Class 1 Comprehension Questions! 1. (TRUE / FALSE) A trait is a characteristic of a living thing. TRUE! 2. How many kingdoms are there? 6 Kingdoms! 3. What is one characteristic do scientist use to help classify organisms? 4. Which most likely has more members” a phylum or a class. Explain. 5. Can organisms that belong to different kingdoms be in the same phylum? Explain why or why not. Comprehension Questions! 6. (TRUE /FALSE ) We can see microorganisms without a microscope. FALSE! 7. What kind of serious disease can protists cause? Malaria 8. What are the six kingdoms? Archaea, bacteria, protists, fungi, plants and animals. 9. (TRUE / FALSE) ALL bacteria is harmful. FALSE! 10. How many species have scientist named? 1.7 million Classifying Living Things Class 2 Vocabulary! •Classify- is a characteristic of a living thing. Why do we classify things? Vocabulary! •TRAIT- is a characteristic of a living thing. Vocabulary! •Kingdom- is the largest group into which organisms can be classified. How are living things classified? • Scientist study the different traits that organisms have to classify them. • They can look at: • Body form • How an organism gets food • How, or if, it moves • The number of cells Classifying Organisms - Read a Chart KINGDOM NUMBER OF CELLS NUCLEUS FOOD MOVEMENT Archaea Bacteria Protists Fungi Plants Animals One One One or Many One or Many Many Many No No Yes Yes Yes Yes Makes Own Food or Gets Food Makes Own Food or Gets Food Makes Own Food or Gets Food Gets Food Makes Food Gets Food Yes Yes Yes No No Yes How are animals grouped within a Kingdom? All animals belong to the same Kingdom because they move and get food from other organisms. After Kingdom there are six smaller groups. Each group below Kingdom becomes smaller and more specific. The smaller the group, the more similar the organisms are to each other. Phylum Class Order Family Genus Species How to remember The Six Kingdoms How did scientists divide living things? The largest group is called the Kingdom. ALL members have the SAME TRAITS. Most of the remaining kingdoms are tiny organisms called microorganisms What are they? They are living things that are too small to be seen with just your eyes. Bacteria Did you know? Even though we think of bacteria as something bad that can cause diseases, some bacteria are helpful. They are even inside your body helping break down your food! Bacteria Bacteria are very small organisms. They are single-celled and do not have a nucleus. Some bacteria break down dead plants and animals for food, others make their own food. Archaea Archaea are tiny, simple They are often found in lakes or organisms. They are single-celled hot springs and can cause color (only have one cell) organisms changes like the pictures below. without a nucleus. Fungi Some fungi are microorganisms. They have a cell nucleus. Like plants, they have a cell wall. Like animals, they do not have chloroplasts so they cannot make their own food. Fungi But there are some good types of Fungi too! Protists Protists are single-celled organisms with a nucleus. Some protists make their own food, others eat other organisms for food. Algae is a type of protist Protists Many protists form part of plankton and are very important for the ecosystem Some protists are helpful, they are a food source for other animals. Other protists can cause serious diseases, like malaria. How are organisms named? Scientists use the organism’s Scientists had to find a very genus and species. Sometimes specific way to name organisms organisms placed in similar so they don’t get confused groups are similar to each other between two similar animals. (like wolves and dogs) Scientists have named 1.7 Million species. Read a Diagram: Wolves vs. Dogs Comprehension Questions! 1. How can you tell the difference between protists and bacteria? 2. How can observing cells under a microscope be useful when identifying organisms? 3. How can classification of a poisonous organism help save someone’s life? 4. Plants, animals, fungi and ____________ are the four kingdoms that have organisms with many cells.
