Life ScienceUnit 1 Chapter 4 Lesson 2 How Scientists Order Living Things
How do we find a student? • How would you give a new exchange student directions to get to see you at the Academy?
Narrowing it Down • When giving directions, we start with a large and broad direction such as fly to Pittsburgh • As the directions get closer to you, they get more specific
How does this apply to Taxonomy? • Scientist use a “Map” to help classify and identify animals • All living things are classified under 7 categories • Each category gets more specific as it gets to the last step
What’s in a Name? • We identify a living thing by binomial nomenclature with is the Genus then Species • Example: Homo Sapien • Homo is the Genus • Sapien is the Species
Speciation • Species- A group of organisms that can mate with each other • If they can mate and produce fertile offspring they are put into the same species • If they cannot produce fertile offspring, they cannot be classified as the same species • Example: Mule, Hinny, Liger
Kingdoms • There are five kingdoms we use in the modern classification system • 1. Kingdom Plantae- includes all green plants • Examples: Blue Spruce, Fern, Ginko, Grass, Moss, Oak Tree, Rose, Tomato Plant
Kingdoms • 2. Kingdom Animalia- contains all animals, vertebrates and invertebrates • Example: Earthworms, Piranha, Tiger, Rat, Lobster, Spider, Blue Whale
Kingdoms • 3. Kingdom Fungi- contains all fungi • Fungi- non-green organisms that reproduce from spores and absorb their food • Examples: Portobello Mushrooms, Yeast, Mold
Kingdoms • 4. Kingdom Prokaryotae- Contains all species of bacteria • Example: E. Coli
Kingdoms • 5. Kingdom Protoctista- contains organisms that have a nucleus (usually one celled) that do not fit into the other categories • Examples: Amoeba, Euglena, Green Algae
Viruses • Viruses are not classified as living even though they reproduce • They need a host cell to reproduce, therefore they are not self-sustaining, so they are non living
