Caption: Light microscope footage of barium sulphate crystals (square) in the terminal vacuole of a desmid. The crystals appear as small square objects, exhibiting Brownian motion due to impacts from water molecules. Their function is unclear. Desmids are a common group of freshwater single-celled algae that have intricate cell walls.
