MOSS
Moss
Small non-vascular plants (Bryophyta).
Highly resilient, pioneer species in extreme habitats (Antarctica, deserts, volcanic fields).
Occur worldwide except salt water; prefer moist, shady sites.
Example: Schistostega pennata (dragon’s gold).
Environmental Significance
Natural sponges → absorb water, maintain soil moisture.
Stabilise soil and prevent erosion.
Regulate ground temperature (protect roots; slow ice thaw).
Enable ecosystem formation in barren areas.
Support biodiversity via microhabitats.
Bioindicators for heavy metals, nitrogen, acidic deposition.
News Highlight
Moss spores survived 9 months in space outside ISS.
80% reproduced after returning to Earth.
Shows extreme resilience; potential for space ecology and future extraterrestrial habitat support.
