Largest kingdom
Most people identify
them as disease causing
(pathogens)
Live in all
environments
Cyanobacter

Protista
Mostly
Unicellular
Autotrophic (plant-like
protists)
Heterotrophs (animal-like
protists)
External heterotrophs
(decomposer/fungi-like
protists)
Microscopic simple organism
with no membrane structure
enclosing genetic information
(usually circular). Contains
ribosomes, yet no membrane
bound organelles present in its
cytoplasm
More complex (compared to
prokaryotes). Contains it
genetic material in a membrane
enclosed nucleus. Has the
presence of ribosomes and
membrane bound organelles
(including a mitochondria)
Cell displays behaviors of more
complex kingdoms
Most are free-living
and may contain
structures involved in
movement: cilia,
flagellum, or
pseudopodia
Many non-motile
protists release spores,
where they enter the
cell of other organisms
and live as parasites
Most atmospheric
oxygen comes from
algae (plant-like protist)
found on the ocean’s
surface
Euglena,
Paramecium
, Algae
Fungi

Multicellular
External
Heterotrophs/Decomposers
More complex (compared to
prokaryotes and protists).
Contains it genetic material in a
membrane enclosed nucleus.
Has the presence of ribosomes
and membrane bound
Was once thought to
be part of Plant
Kingdom.
Do not produce their
own food
Produce spores
during its life cycle

Multicellular
Internal Heterotrophs
No
organelles (including a
mitochondria).
Does not digest food, rather
than releases toxins through
cell walls to break
down/decompose materials and
absorb nutrients through their
environment.
Structures include
hyphae, mycelium, and
fruiting bodies
More complex organisms that
uses levels of organization.
Include a range of complex
structures.
Develop tissues and organs
Contain chloroplasts
(photosynthetic organelles that
contain chlorophyll) and are
characterized as containing a
large central vacuole (mainly
composed of water and aids in
cells rigid structure/increases
cell volume). Mitochondria is
also present.
More complex organisms
(overall) when compared to
other kingdoms.
Use levels of organization
Cells tissues organs
organ systems
Defined with presence of
mitochondria (involved in
energy production) and the
presence of centrioles (apparent
during cell division)
Distinctive sexual life
cycle (alteration of
generations) known as
the sporophyte plant
and gametophyte plant.
Vascular plants
contain complex
structures such as
stomas (involved in gas
exchange) as well as the
xylem and the phloem
(involved in transport of
nutrients and water)
Grass,
Trees,
Flowers
Majority consists of
invertebrates (lack a
backbone)
