How do lichens survive in Antarctica?

  • Lichens have been collected from as far south as 86°30'. Lichens have adaptations that enable them to survive in Antarctica. They are able to exhibit net photosynthesis while frozen at temperatures as low as −20 °C. They can absorb water from a saturated atmosphere when covered by snow. Snow cover provides protection from the elements.

What are some interesting facts about lichens?

  • Some lichens, in an experiment, survived a bath in liquid nitrogen at minus 195 degrees. Some lichens have even been found only about 400 km from the South Pole. Lichens can be all sort of colours.

Can lichens survive in liquid nitrogen?

  • Some lichens, in an experiment, survived a bath in liquid nitrogen at minus 195 degrees. Some lichens have even been found only about 400 km from the South Pole.

Why do lichens grow in the snow?

  • Snow cover provides protection from the elements. Most growth appears to occur when lichens are beneath at least a thin protective layer of snow. Lichens can survive long periods of drought in a dry and inactive state. In continental Antarctica, many lichens are able to absorb water vapour from snow and ice.
