Protists
Protozoins with flagella
flagellates use long wip like tenticals to move
flagellate may have more than one flagella
some protozeans live inside the body of other organisms
some protozeans can cause harm to the host
when a protozean and a host benifit from each other it is called mutualism
diatoms
they are unicellular protists
they have glass like cell walls
they are a source of food for heterotrophs in the water
when they die their cell wall collects on the bottom of oceans and lakes
What are protists?
they are eukaryotes that are nit classified as a plant, fungi, or animals
mosts protists are unicellular
some of them are heterotrophs
animal like protists
animal like protists are heterotrophs
they can move from place to place to obtain food
they are all unicellular
Protozoans with pseudopods
Pseudopods form when cytoplasm flows toward one location an the rest of the organism follows
amoebas use them to move away from bright light
small particuls in water can pass thought the cell membrane
Protozoans with Cilia
the cells of ciliates are complex
ciliates have a sturcture call cilia
Parmicia have more that one nucleus
dinoflagellates
they are unicellular algae
they are a variety of colors
they are glow in the dark. they can light up the surface of the ocean
euglenoids
they are green unicellular algae that live in fresh water
they are heterotrophs if sun light is not avaliable
they can be autotrophs when there is sunlight
Brown algae
brown algae attaches to rocks
they have gas filled sacks called bladders
people eat it
red algae
people use red algae for food
it is found in the water
green algae
they are unicellular
they are related to plants that live on land
slime molds
some slime mold are so small that people need microscopes to see them
fungus like protists are all heterotrophs
