Kingdom Protista - Animal-like Protozoans
Amoebae
Flagellates
means “change shape”
Euglena
unicellular – uni = one
Heterotrophs - consume food for energy
unicellular – uni = one
uses pseudopodia (false feet) to move
The Pseudopodia (false feet) surround food and eat it – process is
called = phagocytosis
The captured food becomes a Food Vacuole
Food is digested by the lysosomes
Euglena are both Heteotrophs and a Autotrophs.
o Heterotrophs – Euglena consume food for energy. Euglenas
can eat nutrients by absorbing them across their cell membrane
when light is not available.
Contractile Vacuole – pumps out excess water so amoebae does not
burst
AND
Amoebae has a Nucleus – containing DNA - Reproductions occurs
through mitosis – called binary fission
o Autotrophs – self- feeding –Euglena make their own food using
chloroplasts and photosynthesis. Chloroplasts in the Euglena
trap sunlight that is used to make food during photosynthesis.
live in ponds or puddles
Parent cell
Nucleus divides
Cytoplasm divides
Two daughter cells
Eyespot at the anterior of the cell detects light
FLEXIBLE cell membrane allows amoebae it to CHANGE SHAPE – it
has NO cell wall
Amoebae live in stagnant ponds, puddles, and inside people
2 kinds of cytoplasm
o endoplasm - darker cytoplasm in the interior or center of the cell
o ectoplasm – clearer cytoplasm around edges of cell membrane
Cyst – in dry or cold periods, the amoeba creates a hard-walled
covering to protect itself
Pellicle – thick outer membrane surrounds the cell that helps the
euglena scrunch up and move like an inchworm
Euglena has a nucleus containing the DNA and controls the cell’s
activities. The nucleolus is inside the nucleus.
Contains cytoplasm
Contractile Vacuole- removes excess water or the cell would
explode– Contractile Vacuoles are star -shaped
Amoebae can cause Amebic Dysentery – a person can get cramps
and diarrhea by drinking contaminated water – water not filtered or
purified.

Kingdom Protista - Animal-like Protozoans
Ciliates
Sporozoa
Paramecium
Sporozoa DO NOT move
unicellular – uni = one
Parasitic – any protozoan organism that lives on, in, or within another
organism
Heterotrophs - consume food for energy
Example
live in stagnant ponds
part of the food chain
Plasmodia Life Cycle
eat algal scum
chsweb.lr.k12.nj.us/.../protista/protists.htm
move using cilia – tiny hair –like projections
Cannot change shape - Pellicle – thick outer membrane surrounds
the cell and helps the cell move
Contractile Vacuoles removes excess water - star shaped
Heterotrophs – Paramecium consume food for energy. The food
enters the oral grove then moves to the mouth pore, then to
gullet and then to food vacuoles
Mosquito bites a
human infected
with malaria and
picks us
plasmodium cells
Plasmodia sporozoa
reproduce and migrate
to the mosquito salivary
gland
The infected mosquito
bites another human
and injects saliva that
contains Plasmodium
sporozoites
Undigested food moves to anal pore
trichocysts – tiny threads to entangle a predator
Sporozoites infect
the lever of the
human and multiply
and infect the red
blood cells
Paramecium have the ability to avoid or move away from negative
or unpleasant things
2 kinds of cytoplasm
o ectoplasm – cytoplasm around edges of cell membrane
o endoplasm - cytoplasm in the center of the cell
The infected red blood
cells burst, and release
more cells that infect
other red blood cells.
The person becomes very
sick with malaria.

Malaria cells
reproduce inside the
red blood cells
