Question

Identify the characteristics of plant-like protists. Check all that apply.

all contain cell walls

autotrophs

unicellular

all are stationary

Answer 1

Only "autotrophs."

Explanation: plant-like protists (algae) perform photosynthesis, so they are primarily autotrophic. They do not all have cell walls (e.g., Euglena has a pellicle), they are not all unicellular (many algae are multicellular, like kelp), and they are not all stationary (some, like dinoflagellates and euglenoids, are motile).
