3. Animal-like protists consume other organisms.
heterotrophs
single-celled
move

4. Plantlike protists are photosynthetic.
single-celled, colonial, or multicellular
no roots, stems, or leaves
Pediastrum kelp

5. Funguslike protists decompose dead organisms.
heterotrophs
can move, whereas fungi cannot
dog vomit slime mold

6. Protists are difficult to classify.
Protista is one kingdom in the domain Eukarya.

7. Protist classification will likely change.
Have many phyla that are very different.
Some protists are not closely related.
Molecular evidence supports reclassification.

8. Conclusion
Molecular evidence will probably lead to the splitting of the protist kingdom into more groups.
