Biol 1401 Evolution and Bryophytes Review Feb 21 st , 2011  Ch. 15, 20 1. What are ecotypes?-  a subdivision of an ecospecies consisting of a  population that is adapted to a particular set of environmental  conditions 2. Plants started to develop from algae (move from water to land) around  400   million years ago. 3. What are the two mechanisms that plants developed to reduce the water  loss for their survival on land?-  produced a waxy fatty cuticle to prevent  water loss 4. If a plant is placed in a particularly humid environment, will the water move  into or out of the guard cell?  Out, because the stomata opens when in a  humid environment 5. How does the water movement eventually influence the shape of the  guard cells and the opening and closing of the stomata?  Through the  Turgor movements 6. The early plant group, Bryophytes, absorb water from plant surface.
