What is protist?
• Protists are eukaryotics. • kingdom Protista, mostly classified by how they move
– Protists– fungus-like – plant-like protists.
• Phacus Giant Kelps
Protozoan• Like animals, animal like protists are called protozoans and
they are heterotrophs but unlike animals, they are unicellular.
• It could be classified as protozoans with pseudo pods, Cilia, Flagella and others.
• Protozoans– pseudopods
• Pseudopods bulges of cytoplasm oozes.
• Protozoans with Cilia
• Ciliates hairlike structures.– move,– obtain food – sense the enviroment.
• Has complex cells
• Protozoans with Flagella
• Flagellates and uses tails to move
• Most Flagellates have one to eight long, whiplike flagella that help them move.
• Other Protozoans
• Sporozoans– Floaters – many are parasites
• Sporozoans feed on the cells and body fluids of their hosts.
Fungus like Protists
• Second group of protists are fungus like protists,.
• Fungus like protists are heterotrophs, have cell walls, and use spores to reproduce.
• Water molds and Downy Mildews
• Most water molds • Downy mildews
– live in water or in moist place.
• It also attacks crops and fishes.
• Slime molds
• Slime molds – live in moist soil and on decaying
plants and trees.– They are often beautifully colored
Plant like protists• Plant like protists, which
are commonly called algae , are even more variad than the animal like and the fungus like protists.
• They are aututrophs like the plants.
• Euglenoids
• Euglenoids are green and unicellular.
• Found in fresh water (mostly)
• They could be heterotrophs under certain conditions.
• Dinoflagellates
• Dinoflagellates are unicellular.
• Covered by stiff plates that look like a suit of armor.
• They are any colors.
• Green Algae
• Contain green pigments• Quite diverse• Most are unicellular• Some from colonies and
few are a multicellular.
• Red Algae
• Most are multicellular seaweeds.
• It could grow 260m below the sea level.
• Some are used in ice creams and hair conditioners.
Brown Algae
• Most seaweeds are a brown algae.
• In their brown pigment, there are green, yellow, and orange pigments.
• It flourish in cool, rocky waters.
