Cell death due to the evaporation of the water on a microscope slide is a phenomenon seen by just about everyone who has spent serious time observing the creatures in a drop of pond water. One function of the cell that can continue to the very end is the contraction of the contractile vacuole. This video shows a vacuole contracting after the cell has completely ruptured. The organism is a Frontonia, a large ciliate found in my local pond. Brightfield, darkfield, and phase contrast illumination is used. https://www.youtube.com/watch?v=HYR0YtVo7ac
Thanks, Rik! I just kept trying different free YouTube soundtracks until I found one that ended nicely with the end of the video.rjlittlefield wrote:Masterful timing on the sound track!
I must confess to serial protist murder as I've seen many of them expire due to evaporation of the water under the cover slip. With this Frontonia, its end seemed dramatic enough to justify doing a video.
