Pollen , coal and stems are evidences that plants existed in Antarctica.
Explanation:
- Pollens being highly resistant to temperature changes due to the presence of sporopollenin must have remained preserved in ice covered continent of Antarctica.
- Pollens are reproductive units of Plant that suggest existence of plants in the Ice covered land.
- Coal is formed as the fossilization of plants under anaeorobic conditions and high pressure. thus, this also suggest the existence of plants.
- Stems are plant parts thus clearly is an evidence that plants existed there.
