Commercial slide of Volvox showing daughter colonies inside parent colony

The following photos show daughter colonies inside Volvox colonies – blue circles within the blue circles.

I used x10, x20 and x40 objectives for these photos in bright field. Unable to get dark field even with x10 objective for this slide for some reason. Best I obtained was a sort of partial oblique illumination which you can see on photo with the partially dark background.
