Since new discoveries have revealed that life in Antarctica is mysterious -- Lake Vostok contains life and has been buried under the ice for millions of years -- it is unclear what percentage of the continent can sustain (microbial) life.
Visible plants, however, are only found in the Antarctic Peninsula, a small portion of the continent.
Given these unknowns, a percentage would only be a guess.
Scientists who study the health of planet earth in Antarctica are not chartered with the challenge to 'help sustain life' in Antarctica. There is no animal life to sustain and 98% of the continent is covered by an ice sheet.
Visible plant life in Antarctica can be seen mostly on the Antarctic Peninsula.
Antarctica is not known for plant life, whatever the season.

To sustain life, a planet must have oxygen and a variety of gases, plant life, strong enough gravity and enough clean water.
Very desolate, cold and extremely windy. Very little, to no plant life grows on this continent, at least not enough to sustain a viable animal population like what's found on other continents.
Fertile soil is soil that is able to sustain plant life.
Oxygen for the survival of advanced life forms. Glucose for the energy of the plant. Water to sustain the plant's life, and drive chemical reactions.
Soil provides the necessary nutrients plant need to be able to sustain life.
It is too cold and there is not enough vegetation to sustain a herd of giraffe's.
Deserts occur when there isn't enough rainfall to sustain a normal amount of plant life.
