A desmid is a single-celled algae
And then there were two! Watch this mesmerizing time lapse video of a desmid dividing. Desmids are single celled, microscopic algae that are beautifully symmetrical. Each cell has two half-cells connected in the middle by the cell nucleus.
Did you know? Desmids thrive in clear, nutrient-poor and unpolluted fresh water. They are considered an “indicator species” of water quality because they disappear when water turns murky.
