Summary
Most protists are unicellular, eukaryotic organisms with animal-like, plant-like, and fungus-like species. However, there are some protist that are multicellular. Both unicellular and multicellular protists are different from each other in the way they obtain their food, which can be autotrophic or heterotrophic, depending on species. They can grow in colonies without the tissue differentiation seen in higher eukaryotic organisms. They fill important niches in ecosystems, acting as primary consumers or developing parasitic relationships with other organisms. They also act as decomposers, breaking down dead organic material and returning essential nutrients to the soil.
When you have completed this lesson, you should be able to:
identify the three main types of protist
identify the three types of locomotion used by protozoa
compare the six major phyla of plantlike protist
discuss the three phyla of fungus-like protist, their role in the ecosystem, and how they differ from true fungi
I kinda need help on this assignment
