Protists, as a group, represent one of the kingdoms of organisms in the eukaryotic domain. In the other kingdoms, the organisms grouped within a kingdom are very closely related and share many unifying features. The many different organisms grouped as protists are not necessarily closely related, and many different types of traits are represented among them.

Review the following list of statements, and select which statements are correct descriptions of protists. Check all that apply.

Protists represent both heterotrophic and autotrophic nutritional modes.

Some protists are colonial.

No protists are multicellular.

The phylogenetic tree displayed here shows the evolution and relationships between different major protist groups, as scientists currently understand them. It also shows how these different groups of protists are related to animals, fungi, and land plants. The protist groups are highlighted in tan boxes. As the tree moves from left to right, each split indicates where major groups diverged from one another and evolved along different paths. The fewer splits between different groups of organisms, the more closely they are related.
According to this phylogenetic tree, are the protists known as amoebozoans more closely related to the protists known as choanoflagellates or to fungi?

**Phylogenetic Tree of Eukaryotic Evolution**

The diagram presented is a phylogenetic tree illustrating the evolutionary relationships among different groups of eukaryotic organisms, originating from ancestral cells. The tree is a hierarchical branching structure that shows how various groups are related through common ancestry.

**Key Groups and Their Position:**

1. **Ancestral Cells**: The base of the phylogenetic tree, representing the common origin of all listed eukaryotic groups.

2. **Flagellated protozoans**: A group of primitive eukaryotes characterized by the presence of flagella, which are used for movement.

3. **Rhizarians**: Protists that include many amoeboid species, often characterized by intricate mineral skeletons.

4. **Alveolates**: A diverse group that includes ciliates, dinoflagellates, and apicomplexans, with the presence of alveoli (small sacs) beneath their cell membranes.

5. **Stramenopiles**: A group that includes diatoms, golden algae, and brown algae, known for their distinctive flagella with hair-like projections.

6. **Red Algae**: Photosynthetic, mostly marine, algae known for their red pigmentation due to phycoerythrin.

7. **Green Algae**: Photosynthetic algae closely related to land plants, sharing similar pigments and chloroplasts.

8. **Land Plants**: Multicellular organisms that primarily live on land, capable of photosynthesis.

9. **Amoebozoans**: This group includes various amoeba species that move via pseudopodia and ingest food by phagocytosis.

10. **Fungi**: A kingdom of eukaryotic organisms that includes yeasts, molds, and mushrooms, primarily known for decomposing organic material.

11. **Choanoflagellates**: Unicellular and colonial flagellates considered to be the closest living relatives of animals.

12. **Animals**: Multicellular eukaryotic organisms that form the kingdom Animalia, characterized by their ability to move, respond to their environment, and consume organic material.

The tree structure shows branching points, each representing a common ancestor shared by the groups diverging from that point. It demonstrates the evolutionary paths that have led to the diversity of eukaryotes existing today.
