1
All protists live in moist surroundings.
Where can you find them? All protists live in moist surroundings.
2
Protists are eukaryotic (have a nucleus)
Most (but not all) protists are unicellular (diatoms) Some are multicellular Giant kelps are example of multicellular protists. Protists are eukaryotic (have a nucleus)
3
Scientists have proposed three categories to group protists to help identify them
Animal-like protists Fungus-like protists Plant-like protists
4
ANIMAL-LIKE PROTISTS Animal-like protists (CALLED PROTOZOAN)
able to move from place to place to obtain food Pseudopods (false foot) -temporary bulges in the cell membrane (also helps trap food) Cilia-hairlike projections from cells that move with a wavelike pattern (also helps organism obtain food) Flagella- one to eight long, whiplike appendage heterotrophs (cannot make own food) consume other organisms. many can be parasites Draw an example for each mode of movement
5
FUNGUS-LIKE PROTISTS Fungus-like protists use spores to reproduce
heterotrophs (cannot make own food) consume other organisms. appearance has a fuzzy like covering or a shiny body can group together and form a multicellular mass
7
PLANT-LIKE PROTISTS Plant-like protists Examples algae diatoms euglena
dinoflagellates green in color, this comes from the chlorophyll used in the photosynthetic process. autotrophs (able to produce their own food) containing chlorophyll which helps the organism sunlight (e.g. euglena drawn to light to make own food) most of the oxygen in Earth’s atmosphere is made by algae vary greatly in size unicellular ( e.g. diatoms) multicelluar –(e.g. seaweeds) group together in colonies Some protists cannot move on their own
