Classification of Living Organisms!

KEY TERMINOLOGY • Classification: is the sorting of objects according to their properties to order objects according to a pattern • Dichotomous Key: a tool used to identify organisms based on contrasting pairs of characteristics • Kingdom: is the highest level of biological classification (animals, plants, fungi, protists, and two for bacteria)

ScientificClassification: • kingdomphylumclassorderfamily genusspecies • Example platypus • kingdom: animaliaphylum: chordata class: mammaliaorder: monotremata family: ornithorhynchiadae Genus: ornithorhynchusspecies: anatinus

TheKingdom of Living Things

Single-celledorganism: • Single-celled organisms live everywhere. • They are so small you need a microscope to see them, but you can see signs of their existence (getting food, producing waste, and reproducing).

Bacteria • single-celled organism • performs basic functions: eats, excretes waste, reproduces, and grows • reproduces asexually through binary fission or budding • Microorganism • breaks down remains of dead plants and animals

Bacteria • usedin the body to digest food • used to makeyogurt, cottage cheese, sour cream, sauerkraut, and pickles • also harmful: causes strep throat, lime disease, y tuberculosis. • EX. yeast

Protists • Are mostly singe-celled, some have cell walls, a nucleus, take in food, or make their own food, many can move. • Protistslive in almost any environment that contains water. Many protists, such as algae, are photosynthetic and are vital primary producers in ecosystems, particularly in the ocean as part of plankton. • Other protists, such as the Kinetoplastids and Apicomplexa, are responsible for a range of serious human diseases, such as malaria.

Fungi • Are mostly multicelled, have cell walls, a nucleus, take in food, and cannot move.

Facts about Fungi! • Some can grow to adult overnight, or so it seems… • Fungi absorb their food from their environment. • They decompose other organisms • Fungi reproduce through spores
