PROTISTS
EUGLENA, AMOEBA, PARAMECIUM,
VOLVOX
What is a Protist?
• Kingdom Protista
• Very diverse
single-celled
organisms.
• Eukaryotic
• Less complex with
many different
characteristics.
EUGLENA
• Single-celled Protists
that live in fresh
water.
• Captures and releases
energy- producers
(make their own food)
and heterotrophs (gets
food by eating other
things)
• Some contain
chlorophyll
More Info on Euglenas
• Feedback- Eyespot
helps them sense
light.
• Waste- Contractile
Vacuole holds
excess water and
removes it from the
cell.
• Movement- Flagella
• video
More Info on Euglenas
• ReproductionAsexual (binary
fission)
• Specialized Needsshape does changes
easily so it can
move around
AMOEBA
• Found in
freshwater and
salt water around a
lot of dead and
decaying material.
• Captures and
releases energyparasites, they get
energy by invading
other organsisms
More Info on Amoebas
• Feedbackpseudopodia (false
feet)
• Waste- Contractile
Vacuole holds
excessive waste
• Movementpseudopodia (false
feet)
• amoeba video
More Info on Amoebas
• ReproductionAsexual (binary
fission)
• Specialized Needsn/a
• Amoeba eating
PARAMECIUM
• Found in
freshwater. This is
a single celled
organism but is
more complex that
other organisms.
• Captures and
releases energyCilia sweep food
into food
passageway.

Paramecium Continued…
• Feedback- n/a
• Waste- Anal Pore
(food waste is
removed) and
Contractile Vacuole
(water waste)
• Movement- Cilia
(tiny hairs that
move back and
forth.)
Paramecium Continued…
• ReproductionSexual (two
Parents)
• Specialized NeedsSpecialized
Function: Two
nucleuses
(Macronucleus and
Micronucleus)
VOLVOX
• Found in ponds
ditches and puddles.
• Composed of a
colony of tiny
flagellate cells.
(more than 50,000
cells)
• Often times called
algae.
Volvox continued…
• Captures and
releases energyphotosynthesis and
flagella help bring
in nutrients.
• Feedbackeyespots to help
sense light.
• Waste- n/a
Volvox continued…
• Movement- Many
flagella help move
it.
• Reproductionasexual and sexual,
daughters colonies
created.
