Description The seasonal development of plastids in beach leaves is demonstrated in series of microscopic shots:
  • Precursors of chloroplasts (proplastids) in the shoot
  • Maturing chloroplasts during leafing
  • Mature chloroplasts in summer leaves
  • Degeneration of chloroplasts to chromoplasts in the autumnal leaf
A video shows a beach bud unfolding in time lapse.
   
 
Note: The Shockwave-modules are merely suitable for the internet because of the still very low speed of data transfer.
