What sets these apart from other plants, like mosses, lichens, and fungi, is their ability to photosynthesize through their vascular system. Antarctica’s isolated location means that the plants there have not developed natural protections against new, foreign species. A few intrepid researchers will begin an arduous journey to Antarctica on Dec. 20 to conduct plant cultivation investigations in an extremely remote region of the world. These plants are young UK plants, produced in the UK, that are not yet forming a trunk. East Antarctica is a unique and fragile ecosystem with very low species diversity for both plant and animal kingdom. There’s also a lack of moisture as Antarctica is really a desert and receives less than two inches of rain annually.

The Southern Ocean is a key component of this system. Other birds. because of its role in circumpolar transport of water. Plant colonies often thrive in these areas because of the warmer temperatures and the availability of free water from steam and melting snow or ice. Changes will be more drastic in the marine environment, where climate change is likely to have profound effects on marine microbes. If the sinking of cold water off Greenland is interrupted by icecap meltwaters, circulation from the Atlantic will be reduced. This is because Antarctica does not have much moisture (water), sunlight, good soil, or a warm temperature.Plants usually only grow for a few weeks in the summer. Pages 165-199.

A few plants have nevertheless found a way to adapt to these extreme conditions: terrestrial plant growth is limited in ice-free areas, and the diversity of species is low.
