Protists
What is a Protist
Protists are eukaryotes that cannot be classified as animals, plants, or fungi.
-
Plantlike Protists
Plantlike protists, which are commonly called algae are extremely diverse
Like plants, algae are autotrophs
Algae exist in a wide variety of colors because they contain many types of pigments--chemicals that produce color.
Diatoms
-
Many diatoms can move by oozing chemicals out of slits in their cells walls. They then glide in the cells.
Dinoflagellates
-
-
Many dinoflagellates glow in the dark! They light up the ocean floor when disturbed by a boat passing or a swimmer
Euglenoids
-
-
When sunlight is available then they will become autotrophs and when there is no sun then they are heterotrophs
Red Algae
-
Their red pigments is good for absorbing the small amount of light that is able to reach deep ocean waters.
They use the red algae in things like ice cream and hair conditioner. In Asia they eat it fresh, dried, or toasted
Green Algae
-
-
-
Some scientists think that green algae belong in the plant kingdom because it has the same green pigment as plants.
Brown Algae
-
Many brown algae have gas-filled sacs called bladders that allow the algae to float upright in the water.
Funguslike Protists
-
Like fungi, funguslike protists are heterotrophs, have cell walls, and use spores to reproduce
Slime Molds
-
They live on forest floors and other moist, shady places.
-
They start as tiny, microscopic amoeba like cells that grow to be a bigger cell. Then part of the slime falls off so that piece of slime will grow and do the same thing.

Animal-Like Protists
Like animals, animals-like protists are heterotrophs, and most are able to move from place to place to obtain food
Protozoans are unicellular. Protozoans can be classified into four groups, based on the way they move and live.
-
Protozoans With Flagella
-
When both partners benefit from living together, the relationship is a type of symbiosis called mutualism
