Plants - Chapter 9
Plants are awesome, with photosynthesis being the most disruptive invention ever! Join Professor Lindsay Turnbull from the University of Oxford to understand why Plants don't have faces, so we don't know what they're thinking, and can even (horror!) write them off as boring. In this video, we examine the evolutionary history of the land plants: from an ancestral alga to the diversity of modern flowering plants that cover our planet today. We will see how plants stole the technology for photosynthesis - undoubtedly the most disruptive invention of all time - and how their activities changed the biosphere forever. Finally, we explore the range of features that allow a large tree in full leaf to suck up a tonne of water every day.
