This protist has large anterior flagellum and is a mixotroph: (select all that apply)Group of answer choicesTrypanosoma sp.Paramecium sp.Euglena sp.

To determine which protist has a large anterior flagellum and is a mixotroph, let's analyze the options provided based on their characteristics:

1. Trypanosoma sp.: This genus includes parasitic species that typically have a flagellum, but they are primarily known for being heterotrophic and parasitic, not mixotrophic.

2. Paramecium sp.: Paramecia are ciliated protists that primarily feed on bacteria and are heterotrophic. They do not possess a flagellum as their primary mode of movement is through cilia, and thus do not meet the criteria.

3. Euglena sp.: Euglena are well-known for their large anterior flagellum and are considered mixotrophs because they can perform photosynthesis (due to the presence of chloroplasts) while also being able to ingest food particles in darkness.

Conclusion

Based on the characteristics of each protist, the correct answer to the question is:

• Euglena sp.: This is the only protist that possesses a large anterior flagellum and is classified as a mixotroph.

Thus, select Euglena sp. as the answer.
