Dr. Mcfarland was able to take this picture for me. it is a real good shot. The terminal vacuoles at the cell tips hold vibrating crystals of barium or calcium sulfate, the function of which are unknown. Brownian motion causes these microscopic particles to move erratically due to the impacts of collisions with the surrounding liquid molecules in which they are suspended. This explanation is from a page of Connecticut College's website. It is describing the red ball of crystals at the end of this desmid.
