The second film<\/strong><\/a> shows cellular organization in color. The nucleus containing the genetic material is visible in blue. The chloroplast where photosynthesis takes place is in green. It captures atmospheric CO2 in a central zone called the pyrenoid, shown in gray. This CO2 is used to make sugars, which polymerize into starch, a giant sugar reserve shown in violet. This starch is at the ends of protuberances that decorate the surface of the chloroplast. This sugar is available to the mitochondria, in yellow, a cellular structure that provides Sanguina<\/em> with energy during the night. Finally, the cell is filled with lipid droplets, visible in red, which form a carbon reserve for spending long months in the snow… Thanks to this work, published in the international journal Nature Communications<\/em><\/strong><\/a>at the end of 2023, we’re beginning to better understand how these tiny cells can thrive in the unique environment of snow!\r\n\r\n[\/vc_column_text][vc_video link=”https:\/\/www.youtube.com\/watch?v=N7c4l6Ul3dE” css=”” title=”Film 1″][vc_video link=”https:\/\/www.youtube.com\/watch?v=LGdmblWWUak” css=”” title=”Film 2″][\/vc_column][\/vc_row][vc_row css_animation=”” row_type=”row” use_row_as_full_screen_section=”no” type=”full_width” angled_section=”no” text_align=”left” background_image_as_pattern=”without_pattern”][vc_column][\/vc_column][\/vc_row]<\/div>","protected":false},"excerpt":{"rendered":"
