Question

Describe some differences in protist appearance.

Answer 1

Protists include a huge variety of eukaryotes, most of which are unicellular. They range from algae to slime molds and water molds to protozoa. Algae obtain energy by photosynthesis; heterotrophic protists obtain energy by consuming other organisms. Protists move via flagella, cilia, or pseudopodia. Protists may be uni- or multicellular; may or may not have cell walls; may or may not have photosynthetic pigments; and may or may not have flagella, cilia, or pseudopodia.
