Inside every leaf-cell of the plant one can find up to 100 chloroplasts, the photosynthetic organelles which contain chlorophyll.<br>Those organelles can actively and individually move in a light-dependent manner. Under dim light conditions, chloroplasts sit in a single layer to absorb as much sunlight as possible. The dynamics in this dense two-dimensional configuration of these hemispherical organelles has striking similarities to systems close to a glass transition or supercooled liquids: occasionally a single or several organelles can change neighbors by &#8220;hopping&#8221; between cages, whereas in other regions nothing moves. However, if strong light is turned on the chloroplasts agitate and &#8216;break&#8217; out of their local confinement and can re-arrange towards a light-avoidance state.<br>The proximity to a transition from an arrested to a &#8216;fluid&#8217;-like state serves a biological role: chloroplasts arrange in a way to receive as much light as possible, while maintaining the ability to break out of a two-dimensional glass-like configuration in order to actively re-arrange to avoid photo damage. <\/p>\n\n\n\n<p>More can be read here: <a href=\" https:\/\/doi.org\/10.1101\/2022.04.15.488438\">https:\/\/doi.org\/10.1101\/2022.04.15.488438<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>PhD student Nico Schramma wins the first price of the BioPM Posterawards during the NWO Biophysics conference in Veldhoven with his poster entitled &#8220;Collective chloroplast dynamics in plant cells&#8221; On his poster the PhD student presents his work on a dynamical phase transition observed during the photo-adaptation of the water plant Elodea densa.
