An ecologist is studying Dunaliella salina a single celled algae in a local pond. The pond is located near a construction site and the ecologist wants to know what affect, if any, the construction site is having on the pond, as there has been a steady decline in the Dunaliella salina population. In order to complete their study the ecologist would like to examine the organelles inside Dunaliella salina. If they would like to examine the inner structure of the chloroplasts of an already dead Dunaliella salina, what microscope would be best suited for this task?
