All living things:
1. Are composed of cells
2. require energy
3. reproduce
4. display heredity – pass traits

II. Some Definitions of Life:
Life: The property manifested in functions such as
metabolism, growth, response to stimulation, and
reproduction, by which living organisms are distinguished
from dead organisms or from inanimate matter. (Webster's
Dictionary)
Life: The state of being which begins with generation, birth, or
germination, and ends with death; also, the time during which
this state continues; that state of an animal or plant in which
all or any of its organs are capable of performing all or any of
their functions; used of all animal and vegetable organisms.

KINGDOM MONERA
(monerans)
*1 cell
*no true nucleus prokaryote –
*examples - bacteria,
blue-green bacteria
(cyanobacteria)
KINGDOM PROTISTA (protists)
*1 cell
*have a true nucleus –
eukaryote
*examples - amoeba,
diatom, euglena,
paramecium, some
algae (unicellular), etc
KINGDOM FUNGI
*multicellular
*have nuclei
*mainly do not move from
place to place
*heterotrophic – must get
food (food is digested
outside of fungus)
*examples - mushroom,
mold, puffball, shelf/bracket
fungus, yeast, etc
KINGDOM PLANTAE (plants)
*multicellular
*have nuclei
*do not move
*autotrophic – makes own food
*examples - multicellular algae,
mosses, ferns, flowering plants
(dandelions, roses, etc.), trees,
etc
KINGDOM ANIMALIA (animals)
*multicellular
*have nuclei
*do move
*heterotrophic – must
get food
*examples - sponge,
jellyfish, insect, fish,
frog, bird, lion,
humans
