well..actually even i'm not sure.......but a qn regarding this has cum in the paper .........so best way is to see qns related to this...............
 
the qns is....
choose and arrange any four of the following groups of plants in ascending order of evolution scale:
cycads,gnetales,monocotyledons,rhynia-like,chlorophyta ancestors,dicotyledons and seed ferns
 
ans- chlorophyta ancestors---->rhynia-like------>seed ferns------>cycads----->gnetales--------->dicotyledons-------->monocotyledons
 

Remember Cedric. Remember, if the time should come when you have to make a choice between what is right and what is easy, remember what happened to a boy who was good, and kind, and brave, because he strayed across the path of Lord Voldemort. Remember Cedric Diggory.
