Classification of Living Organisms!

KEY TERMINOLOGY • Classification: is the arrangement of things into groups of similar items. • A Dichotomous Key: is a tool used to identify organisms based on contrasting pairs of characteristics. • A Kingdom: is the highest level of biological classification (animals, plants, fungi, protists, and two for bacteria).

Classification

Dichotomous Key

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

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

Protista • Are mostly singe-celled, some have cell walls, a nucleus, take in food, or make their own food, many can move. • Protista live in almost any environment that contains water. Many protista, such as algae, are photosynthetic and are vital primary producers in ecosystems, particularly in the ocean as part of plankton.

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
