xenobotanical

Xenobotanical refers to the study of alien plant life or plant-like organisms found on planets other than Earth. It encompasses the classification, anatomy, physiology, ecology, and evolution of extraterrestrial flora. Xenobotanists investigate the unique adaptations these organisms may possess to survive in diverse and often extreme extraterrestrial environments, such as varying atmospheric compositions, gravitational forces, radiation levels, and soil chemistries.

The field often draws upon principles of terrestrial botany but must account for the possibility of radically different biological structures and biochemical processes. This could include novel photosynthetic pigments, alternative methods of reproduction, or the use of different solvents for biological functions. Xenobotany is largely a theoretical or speculative science due to the current lack of confirmed extraterrestrial plant life. However, it plays a role in astrobiology, exoplanet research, and science fiction, helping to imagine and understand the potential diversity of life in the universe. Discoveries of extremophiles on Earth have provided models for how life might adapt to alien conditions.
