Classification Notes __________________________________ and other processes have led to an amazing diversity of organisms. Biologists have identified and named about __________________ species so far. They estimate that 2–100 million additional species have yet to be discovered. _______________________ is the science of naming and classifying organisms. EACH LEVEL (TAXON) IS BROADER THAN THE ONE BELOW IT. ____________________________ - 1707 –1778, Swedish botanist, physician, and zoologist. He laid the foundations for the modern scheme of _________________________________________________. In binomial nomenclature, each species is assigned a _______________ scientific name. The scientific name is ____________________________. He is known as the father of modern taxonomy, and is also considered one of the fathers of modern ecology. 1. Which group of animals belong to the homo genus? 2. Which group of animals belong to the Paranthropus genus? 3. Which species still exists today? Linnaeus's System of Classification Linnaeus not only named species, he also grouped them into categories. What is Linneaus’s system of classification? Each level is called a _______________, or taxonomic category. ____________________ and __________________ are the two smallest categories. King Philip Came Over For Grape Soda! Linnaeus taxonomy doesn’t account for ____________________ evidence. The technology didn’t exist during Linneaus’s time. His system was based only on _________________________ similarities. Kingdoms and Domains Five Kingdoms - Scientists realized there were enough differences among organisms to make 5 kingdoms: List the 5 kingdoms: ________________________________________________________________________ Six Kingdoms - Recently, biologists recognized that Monera were composed of two distinct groups: ________________________________________________________. The six-kingdom system of classification includes: List them.____________________________________ ____________________________________________________________ The Three-Domain System __________________________ have given rise to a new taxonomic category that is now recognized by many scientists. The __________________ is a more inclusive category than any other — larger than a __________________. The three domains are: ______________, which is composed of _________________________________________________. ______________, which corresponds to the kingdom _______________________________. ______________, which corresponds to the kingdom _____________________________. Domain Bacteria Members of the domain Bacteria are __________________________________. Their cells have thick, rigid cell walls that surround a cell membrane. The domain Bacteria corresponds to the kingdom Eubacteria. Domain Archaea Members of the domain Archaea are _________________________________. Many live in extreme environments. Their cell walls _________ peptidoglycan, and their cell membranes contain unusual lipids not found in any other organism. The domain Archaea corresponds to the kingdom Archaebacteria. Domain Eukarya The domain Eukarya consists of organisms that have a _______________. This domain is organized into four kingdoms: List the domains: _______________________________________________________________ ______________________________________________ The kingdom ____________ is composed of eukaryotic organisms that cannot be classified as animals, plants, or fungi. Its members display the greatest variety. They can be _________________________; photosynthetic or heterotrophic; and can share ______________ with plants, fungi, or animals. Members of the kingdom Fungi are ______________. Most fungi ________ on dead or decaying organic matter by secreting digestive enzymes into it and absorbing small food molecules into their bodies. They can be either ______________ (mushrooms) or unicellular (yeasts). Members of the kingdom Plantae are ____________________________. Plants are ______________—they cannot move from place to place. Plants have cell walls that contain cellulose. Members of the kingdom ______________ are multicellular and heterotrophic. The cells of animals do not have ______________. There is great diversity within the animal kingdom, and many species exist in nearly every part of the planet.
