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)

Scientific Classification: kingdomphylumclassorderfamilygenusspecies Example platypus kingdom: animaliaphylum: chordataclass: mammaliaorder: monotrematafamily: ornithorhynchiadaeGenus: ornithorhynchusspecies: anatinus

The Kingdom of Living ThingsKingdom Description Described Species

Plantae Mutlicelled, cell walls, nucleus, make their own food, most can move

about 270,000

Animalia Multicelled, no cell walls, nucleus, eat food, most can move

More than 1,500,000

Fungi Mostly multicelled, cell walls, nucleus, take in food, cannot move

About 70,000

Protista Mostly single-celled, some have cell walls, nucleus, take in food, or make their own food, many can move

About 80,000

Bacteria Single-celled, cell walls, no nucleus, take in food or make their own food, some can move

About 5,000

SINGLE-CELLED ORGANISM:

• 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 used in the body to digest food used to make yogurt, 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.

Protists live 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

Now it’s Your Turn!

HOMEWORK #1: Use the information in the chart of kingdoms of living things to finish your flipcharts, but do not include animalia.HOMEWORK #2: Make a dichotomous key for the five kingdoms. Use the list of living organisms below and your flipchart guidebook. Algea, penguin, shiitake

mushroom,plancton, yeast, morel mushroom, banana plant, wolf, sunflower.

…C U later fun-guys!
