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).

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
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
The Kingdom of Living ThingsKingdom Description Described Species
Plantae Mutlicelled, cell walls, nucleus, make their own food, most can’t move
about 270,000
Animalia Multicelled, no cell walls, nucleus, eat food
More than 1,500,000
Fungi Mostly multicelled, cell walls, nucleus, absorb 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, absorb food or make their own food, some can move
About 5,000
Now it’s Your Turn!HOMEWORK #1: Use the information in the chart of kingdoms of living things to finish your flipcharts.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, elephant, shark, liverwort, chanterelle, bee.
…C U later fun-guys!
