Algae Chlamydomonas – Different colors of snow

Algae Chlamydomonas – Freshly fallen snow seems pure white, although the snowflakes are transparent. This is because they reflect white sunlight evenly. We found 100 species of plants that live in the snow, coloring it in green, brown, purple and even blood-red. The last color is represented by monocellular algae from the Chlamydomonas species living in the colonies behind the Arctic Circle. Because they absorb more solar heat than the surroundings, so the snow around them melts, and the algae sink into the pits that cover the ice layer from above. In such micro – greenhouses a constant temperature of around 0 ° C prevails.
