Kingdom Protista - Animal-like Protozoans
Amoebae means “change shape” Flagellates
unicellular – uni = one Euglena
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 Euglena are both Heteotrophs and a Autotrophs. called = phagocytosis o Heterotrophs – Euglena consume food for energy. Euglenas
The captured food becomes a Food Vacuole can eat nutrients by absorbing them across their cell membrane
when light is not available. Food is digested by the lysosomes
Contractile Vacuole – pumps out excess water so amoebae does not AND burst o Autotrophs – self- feeding –Euglena make their own food using Amoebae has a Nucleus – containing DNA - Reproductions occurs chloroplasts and photosynthesis. Chloroplasts in the Euglena through mitosis – called binary fission 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 Pellicle – thick outer membrane surrounds the cell that helps the has NO cell wall euglena scrunch up and move like an inchworm
Amoebae live in stagnant ponds, puddles, and inside people Euglena has a nucleus containing the DNA and controls the cell’s
activities. The nucleolus is inside the nucleus. 2 kinds of cytoplasm o endoplasm - darker cytoplasm in the interior or center of the cell Contains cytoplasm
o ectoplasm – clearer cytoplasm around edges of cell membrane Contractile Vacuole- removes excess water or the cell would Cyst – in dry or cold periods, the amoeba creates a hard-walled explode– Contractile Vacuoles are star -shaped covering to protect itself
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 eat algal scum Plasmodia Life Cycle
chsweb.lr.k12.nj.us/.../protista/protists.htm move using cilia – tiny hair –like projections
Cannot change shape - Pellicle – thick outer membrane surrounds Plasmodia sporozoa reproduce and migrate The infected mosquito the cell and helps the cell move Mosquito bites a to the mosquito salivary bites another human human infected gland and injects saliva that Contractile Vacuoles removes excess water - star shaped with malaria and contains Plasmodium picks us sporozoites Heterotrophs – Paramecium consume food for energy. The food plasmodium cells enters the oral grove then moves to the mouth pore, then to gullet and then to food vacuoles
Undigested food moves to anal pore trichocysts – tiny threads to entangle a predator
Sporozoites infect the lever of the Paramecium have the ability to avoid or move away from negative human and multiply or unpleasant things and infect the red blood cells 2 kinds of cytoplasm The infected red blood o ectoplasm – cytoplasm around edges of cell membrane cells burst, and release more cells that infect o endoplasm - cytoplasm in the center of the cell other red blood cells. Malaria cells reproduce inside the The person becomes very red blood cells sick with malaria.
