•There are more than 10 milliondifferent kind of living things.

•Scientists classify organisms. To do this, they find similar ways in which organisms look, live, eat, move, grow, changeand reproduce.

GROUPING LIVING THINGS

KINGDOMSThe biggest group

MONERA•Are single-celled organisms

that don’t have a nucleus.

•Bacteria make up the entire kingdom.

•Some bacteria are beneficial to us, such as the ones found in yogurt.

•Others can cause us to get sick.

PROTISTS•Are mostly single-celled

organisms that have a nucleus (eukaryote).

• They usually live in water.

•Some protists move around, while others stay in one place.

•Examples of protists include some algae, paramecium, and amoeba.

FUNGI•Are multi-celled organisms.

•Are usually motionless organisms that absorb nutrients for survival.

•They include mushrooms, molds, and yeasts.

PLANTS•Are multi-celled organisms.

•Contain chlorophyll for photosynthesis, a process in which plants convert energy from sunlight into food.

•They make their own food.

•They are fixed in one place.

ANIMALS•Are the most complex organisms on

Earth.

• Animals are multi-celled organisms.

•Eat food for survival, and have nervous systems.

SMALLER GROUPSScientists classify living things into

smaller and smaller groups.The organisms in each group havemore and more things in common.

•Kingdoms are dividedinto groups calledPHYLUM

•Phyla are divided intoCLASSES

•Classes are dividedinto ORDERS

•Orders are dividedinto FAMILIES

•A GENUS is a división of a family.

•A GENUS has one or more species.

•Each different kind of living thing is a species.

•The scientific name of a single type of living thingincludes the genus and species
