  2. I'm not sure if anyone is till reading this, but it could be noted that the pollen grains are different for each type of plant; For insect pollinated plants they are small and sticky whereas they are large and float easily for wind pollinated plants. It could also be noted that the anthers are placed so that insects will brush against them as they reach the ovaries. Thanks for doing this by the way Hannah, it's a big help.
