Where can you find them? All protists live in moist surroundings.

Some protists are unicellular (diatoms) Some protists are unicellular (diatoms) Some are multicellular Giant kelps are example of multicellular protists. Some are multicellular Giant kelps are example of multicellular protists. Protists are eukaryotic (have a nucleus) Protists are eukaryotic (have a nucleus)

Scientists have proposed three categories to group protists to help identify them Animal-like protists Animal-like protists Fungus-like protists Fungus-like protists Plant-like protists Plant-like protists

ANIMAL-LIKE PROTISTS Animal-like protists (CALLED PROTOZOAN) 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) 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) Cilia-hairlike projections from cells that move with a wavelike pattern (also helps organism obtain food) Flagella- one to eight long, whiplike appendage 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

FUNGUS-LIKE PROTISTS 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

PLANT-LIKE PROTISTS Plant-like protists Plant-like protists –Examples algae algae diatoms diatoms euglena euglena dinoflagellates dinoflagellates –green in color, this comes from the chlorophyll used in the photosynthetic process. –Some brown and red algae –autotrophs (able to produce their own food) containing chlorophyll which helps the organism containing chlorophyll which helps the organism sunlight (e.g. euglena drawn to light to make own food) 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) unicellular ( e.g. diatoms) multicelluar –(e.g. seaweeds) group together in colonies multicelluar –(e.g. seaweeds) group together in colonies –Some protists cannot move on their own

Let’s Sing about Protozoans! Let’s Sing about Protozoans! Let’s Sing about Protozoans! Let’s Sing about Protozoans! chorus chorus 1. Amoebas, euglenas, paramecia 1. Amoebas, euglenas, paramecia 2. They're found in the water sometimes in the soil 2. They're found in the water sometimes in the soil 3. They are so small even microscopic 3.

They have a flagellum kinda like a tail 3. They photosynthesize underneath the water 4. They make their own food on the sunny days. Chorus Paramecia 1. It's time for paramecia, another protozoan 2. They move through the water with their cilia 3. they live in ponds, rivers, and puddles 4. they look like a footprint and it's pretty awesome
