Question

A student taking samples from a local creek uses a microscope to identify different microscopic

organisms living in the ecosystem. The student uses a stain to help identify the organisms as
either prokaryotic or eukaryotic. A picture of one of the slides is shown. The student decides
that the two organisms shown on this slide are eukaryotic.

What is the best reason the student can give to support the conclusion that the two organisms are eukaryotic?

Answer 1

The cells are eukaryotic because they have a membrane bound nucleus shown in the picture are the dark blue stained spot in the pictured cells. Prokaryotes do not have membrane bound organelles.
