The AnimalKingdom
All animals:are many-celled
get energy from eating otherliving things

The AnimalKingdom
Animals are divided into twosmaller groups:
vertebrates(with a backbone)invertebrates (without a backbone)

All plants:are many-celled
can produce their own food

Plants are divided into twosmaller groups:
vascular plants (plants with tubes)
nonvascular plants(plants without tubes) Moss

All fungi (plural of fungus):are one-celled or many-celledcannot make their own foodabsorb food from deadorganisms around them
mushrooms mold

All bacteria:are one-celled
do not have a nucleus

The BacteriaKingdoms
Bacteria are divided into twokingdoms:
Ancient Bacteria(found in hot springs and saltwater environments)True Bacteria(found in and on otherorganisms; can cause disease)

The ProtistKingdom
Protists:don’t fit into other kingdoms can have one or many cellssome make their own foodsome eat other living thingssome break down dead organisms
