Question

what kind of flower will go for cross pollination

Answer 1

Hi friend...
usually all the flowers try to show cross pollination bt chasmogamous flowers(open and exposed stamens and style ) show cross pollination as it leads to variation therefore ,for better adaptability in the environment. 
Hope this helps u....

Answer 2

Heya!
____________________________________________________________

All the flowers perform pollination, both self and cross pollination to reproduce..

But is you ever noticed flowers which have their stamen, stigma and style quite open and visible might have the possibility of taking up Cross pollination more than self pollination.
