Protists
Plantlike Protists
Plantlike protists, which are commonly called the algae are extremely diverse. Like plants, algae are autotrophs
-
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 ice cream.
Brown Algae
-
Brown algae also contain yellow, green, and orange pigments
Many brown algae also have gas filled sacs called bladders that allow algae to float upright in the water
-
Diatoms
-
-
Some float near the surface of lakes or oceans and others attach to objects such as rocks in shallow water
Euglenoids
-
Unlike other algae, they have one animal like characteristic-they can be heterotrophs under a certain condition
Green Algae
Most green algae are unicellular but some form colonies, and a few are multicellular
-
Green algae and plalnts contain the same type of green pigment and share other important similarities
Animal-Like Protists
-
Protozoans are unicellular, and they can be classified into four groups, based on the way they move or live
Like animals, animal like protists are heterotrophs, and most are able to move from place to place to obtain food
-
Protozoans with Cilia
-
Ciliates have structures called cilia, which are hairlike projections from cells that move with a wavelike motion
-
Protozoans With Flagella
The interaction between these two species is an example of symbiosis a close relationship in which at least one of the species benefits
When both partners benefit from living together, the relationship is a type of symbiosis mutualism
The third group of protozoans are flagellates, protists that use long, whiplike, flagella to move. A flagellate may have one or more flagella.
-
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
A spore in a tiny cell that is able to grow into organism. Like fungi, funguslike protists are heterotrophs, have cell walls, and use spores to reproduce
-
Slime Molds
They ooze along the surfaces of decaying materials, feeding on bacteria and other microorganisms
Slime molds live in forests and moist, shady places
