Scientists discover how plants breathe -- and how humans shaped their 'lungs'

sciencedaily.com
  • Movement of air through leaf stomata (pores) shapes the internal workings of plants.
  • This discovery changes how we think about plant evolution - until now it was unknown how plants form air channels to provide CO2 to every plant cell.
  • It was also discovered that humans have already influenced how plants breathe by breeding wheat that needs less water.
  • This means that it’s possible to develop crops able to survive in extreme droughts, which are becoming more common due to climate change.
  • Researchers used X-ray CT image analysis on plants with different leaf structures to visualise their cellular structure in 3D.
