A scientific study published in iScience showed that over 80% of moss spores survived nine months in outer space, highlighting the spores' remarkable resilience. According to the study, this survival is primarily attributed to their ability to withstand:
- 1Cold plasma interactions utilized in spacecraft electric propulsion systems
- 2High gravitational and atmospheric pressures during orbital deceleration
- 3Complete absence of chlorophyll during germination in zero-gravity environments
- 4Extreme cosmic radiation and vacuum conditions due to protective, multi-layered spore walls✓
Correct answer
Extreme cosmic radiation and vacuum conditions due to protective, multi-layered spore walls
