Question

what is an example of a protist?
yeast

algae

Explanation:

• Yeast: Yeast is a fungus, not a protist. Fungi have cell walls made of chitin and different modes of nutrition compared to protists.
• Mold: Mold is also a fungus. Fungi are in a separate kingdom from protists.
• Algae: Many types of algae (such as green algae, diatoms, etc.) are protists. Protists are a diverse group of eukaryotic organisms that are not plants, animals, or fungi. Algae can be unicellular or multicellular and have characteristics like photosynthesis (in many cases) that fit within the protist kingdom.

Algae
