PLANTAE

A group of all plants that are found on earth

They can be both; sexual & asexual

Plants have chloroplast and chlorophyll pigment. This is required for photosynthesis

They have photosynthesis

Without plants, life on Earth could not exist

Plants feed almost all of the organisms that feed other organisms

Plantae is the second largest kingdom

Organisms that make their own food

Plants are all multicellular

They show alterations of generations

Consist of complex cells

FUNGI

Unlike plants, fungi are unable to make their own food

They feed off of parts of plants that are decaying inside soil

Most fungi are multicellular

Contain many complex cells

Fungi include mushrooms, mold and mildew

Some are edible while others could kill humans

ANIMALIA

Some of the less complex animals can grow back missing body parts

Also referred to as metazoa

All animals are made up of many different cells

They rely on other organisms for their nutrients

The animal kingdom is the largest kingdom with over 1 million species

They reproduce sexually by sperm & eggs

Include mammals, fish, reptiles, birds and amphibians

Most are free moving

All animals are apart of this kingdom

EUBACTERIA

Some eubacteria can make their own food while others have to find it

Certain Eubacteria are able to induce serious diseases including tuberculosis, meningitis, anthrax, leprosy, cholera and tetanus.

Can be different shapes such as round, comma shaped, or spirals.

Are complex and single celled

Examples of eubacteria include E. coli, Lactobacilli, & Azospirillum

Lack a nuclear membrane

Consist of a single cell lacking a nucleus includes DNA that is a single circular chromosome

Eubacteria in the human guts help with the process in food digestion and synthesis of vitamin K.

Protects the human body from harmful bacteria

ARCHAEBACTERIA

Are known to be the longest living organisms on earth

The name "archae" means ancient

One of the first places archaebacteria were first found was in the hot springs of Yellowstone National Park

Archaebacteria are found in extreme environments such as hot or salty

There are three different groups of archaebacteria: methanogens, halophiles, & thermophiles.

PROTISTA

Protists are eukaryotic, this means they have a nucleus.

Can be found anywhere on Earth where water exists. Even in humans.

Examples of protists: algae, amoebas, euglena, plasmodium, & slime molds

Protists can be parasites

Primarily live in water although some live in soil.

A diverse collection of organisms.

Most are unicellular

They can sometimes be very different from one another

A single cell organism apart of the protista kingdom.

The include all organisms that are NOT bacteria, animalia, plantae or fungi
