Question

Quizplus · Accepted Answer

The presence of an obvious nucleus and oval structures containing green pigment suggests that the microbe is a eukaryote and likely an algae, which are photosynthetic eukaryotes that contain chloroplasts with green pigments. The lack of motility narrows down the choices further, as both algae and protozoa can be either motile or non-motile, but fungi are non-motile and bacteria and archaea do not have a nucleus.
