When he broke in to the tomb of Tutankhamun, he stuck a candle in the hole and surveyed the contents. Here's what the process looks like in a closely related alga (not a desmid, though) called Spirogyra. Watch for mucilage ooze being extruded on the left at :21. Note however that the similarities between B and C are based on the characteristics that define the entire lineage and, in fact, other than these symplesiomorphies there is no derived feature which supports grouping B with C. Put another way, B and C do not share together a unique genealogical history, and thus constitute an unnatural group. With tiny, sculpted bodies and some distinctly unplantlike behavior, desmids are gorgeous botanical oddballs. Start studying Biology Facts Practice 3: Algae.
