This image is of pond water collected from the Turtle Ponds on campus. The sample was collected at 4:50 PM on 4/8/19. The sample was collected by sticking the Falcon Tube into the pond.
In this zoomed out photo, membranes around the particles can be seen, however I don’t know if those are Eukaryota or Prokaryotic cells. To find this out, I would need to get a zoomed in photo to see if there are membrane bounded organelles to make this distention.
