Kingdom
Protista
What
is
a
Protist?
Protists
form
a
group
of
organisms
that
really
do
not
fit
into
any
other
kingdom.
Although
there
is
a
lot
of
variety
within
the
protists,
they
do
share
some
common
characteristics:
•
All
protists
are
_____________.
That
is,
all
protists
have
cells
with
__________.
In
addition,
all
protists
live
in
______________
environments.
•
Protists
can
be
_____________
or
_____________.
Protists
can
be
microscopic
or
can
be
over
100
meters
(300
feet)
long.
Some
protists
are_______________,
while
others
are
________________.
•
Since
protists
vary
so
much,
we
will
group
them
into
three
subcategories:
____________‐like
protists,
____________‐like
protists,
and
____________‐like
protists.
A.
Animal‐like
Protists:
Protozoans
Protists
that
are
classified
as
animal‐like
are
called
_______________
and
share
some
common
traits
with
animals.
All
animal‐like
protists
are
______________.
Likewise,
all
animal‐like
protists
are
able
to
_____________
in
their
environment
in
order
to
find
their
food.
Unlike
animals,
however,
animal‐
like
protists
are
all
______________.
Animal‐like
protists
are
divided
into
four
basic
groups
based
on
how
they
move
and
where
they
live:
Sarcodines
Amoeba
Ciliates
Paramecium
Flagellates
Move
and
capture
food
by
Move
and
capture
food
by
using
pseudopodia
(finger‐
beating
numerous
hair‐like
like
structures).
cilia.
Sporozoans
Trypanosoma
(“sleeping
sickness”)
Move
by
means
of
one
or
more
whip‐like
flagella.
Many
live
in
the
bodies
of
other
organisms.
Plasmodium
(malaria)
Non‐motile
parasites
that
form
spores
during
their
life‐cycle.
B.
Plant‐like
Protists:
Algae
Plant‐like
protists
are
______________
(they
can
perform
photosynthesis).
They
can
live
in
soil,
on
the
bark
of
trees,
in
fresh
water,
and
in
salt
water.
These
protists
are
very
important
to
the
Earth
because
they
produce
a
lot
of
______________,
and
most
living
things
need
oxygen
to
survive.
Furthermore,
these
plant‐like
protists
form
the
base
of
aquatic
food
chains.
These
plant‐like
protists
can
be
________________,
________________,
or
live
in
________________.
The
plant‐like
protists
are
divided
into
four
basic
groups:
euglenoids,
dinoflagellates,
diatoms,
and
algae.
Euglenoids
Euglenida
Dinoflagellates
Diatoms
Algae
Peridinium
Unicellular.
Autotrophic
when
sunny;
heterotrophic
when
dark.
Some
have
flagellum.
Unicellular.
Covered
by
stiff
plates.
Have
2
flagella.
Found
in
ocean.
May
glow
in
the
dark.
Arachnoidiscus
Volvox
Unicellular.
Has
silica
cell
walls.
One
of
the
most
common
types
of
phytoplankton.
Multicellular:
brown
and
red
algae;
Unicellular
and
multicellular:
green
algae.
C.
Fungus‐like
Protists:
Slime
Moulds
and
Water
Moulds
Fungus‐like
protists
are
________________
with
________________.
They
also
reproduce
by
forming
_____________.
All
fungus‐like
protists
are
able
to
move
at
some
point
in
their
lives.
There
are
essentially
two
types
of
fungus‐like
protists:
water
molds
and
slime
molds.

as
