Protists
Animal-Like Protists
-
Like animals, animal-like protists are heterotrophs, and most are able to move from place to place to obtain food
Protozones are unicellular, and they can be classified into four groups, based on the way they move or live
-
Prorozoans With Cilia
Ciliates have structures called cilia, which are hairlike projections from cells that move with a wavelike motion.
-
-
Protozoans With Flagella
The third group of protozoans are flagellates, protists that use long, whiplike, flagella to move. A flagellate may have one or more flagella.
The interaction between these two species is an example of symbiosis a close relationship in which at least one of he species benefits
When both partners benefit from living together, the relationship is a type of symbiosis mutualism
-
Plantlike Protists
Diatoms
-
Some float near the suface of lakes or oceans and others attach to objects such as rocks in shallow water
-
-
Euglenoids
Green, unicellular algae that are found mostly in fresh water
Unlike other algae, they have one animal like characteristic-they can be heterotrophs under a certain condition
Red Algae
-
-
People use red algae in a variety of ways. Carrageenan and agar, substances extracted from red algae, are used in products such as icecream.
Green Algae
Most green algae are unicellular but some form colonies, and a few are multicellular
-
Green algae and plants contain the same type of green pigment and share other important similarities
Brown Algae
-
Many brown algae also have gas filled sacs called bladders that allow algae to float upright in the water
Brown algae also contain yellow, green, and orange pigments .
Plantlike protists, which are commonly called algae are extremely diverse. Like Plants, algae are autographs.

What is a Protist
Protists are Eukaryotes that cannot be classified as animals, plants, or fungi. Because protists are so different from each other you can think of them as the "odds" and "ends" kingdom
-
-
Funguslike Protists
Slime Molds
Slime molds live in forests and moist, shady places
They ooze along the surfaces of decaying materials, feeding on bacteria and other microorganisms
-
A spore i a tiny cell that is able to grow into a new organism. Like fungi, funguslike protists are heterotrophs, have cell walls, and use spores to reproduce
