Potential for Alien Plants on Exoplanets
Considering the conditions on exoplanets, the podcast discusses the possibility of alien plants evolving on these distant worlds. While Earth-like plants rely on chlorophyll pigments and sunlight for photosynthesis, plants on exoplanets orbiting red dwarf stars may need to adapt to different conditions. Research suggests that photosynthesis could occur on these planets, albeit utilizing different pigments and wavelengths of light, potentially leading to the evolution of unique extraterrestrial flora.
