Kindom Brief Description  

Animal

Multicellular organisms that ingest food from an outside source, flexible cells  lacking a stiff cell wall, cells arranged into units called tissue, usually mobile. 

Plant

An organism capable of producing it’s own food; cells containing chlorophylls a  and b, cells possess stiff cell walls, mainly sessile.

Fungi

Heterotrophic (deriving food from an outside source) organisms, filamentous, with  chitin rich cells. Natural decomposers. 

Protista

Monera: 
Single celled organisms lacking  
a membrane-enfolded nucleus.
Eubacteria:

Cell walls containing muramic acids, sometimes appearing in colonies.

Monera: Single celled organisms lacking a membrane-enfolded nucleus.  
Archaebacteria

Cell walls lacking muramic acids, capable of living in extreme regions.
