Video depicts growth of female thalli of Marchantia polymorpha. Pictures were taken for 58 days, 1 picture/hour, starting from a two-week-old thallus. The whole sequence was compressed to 57 sec. After 24 days, far-red light was added, which appears as ‘jumping’ at the tips of thalli. Female sexual organs (archegoniophores) grow upward after irradiation of far-red light.
