Second of all, plants are green because they contain Chlorophyll, not because they block red and blue.
Thirdly, photosynthesis has nothing to do with the colour of plants, it is a process in which use the energy in sunlight to convert Carbon Dioxide and Water into sugars. Which in turn, creates chlorophyll.
Fourth point, if the sun put light in a form that plants couldnt use, then plants wouldnt exist on Earth
Almost every point you made is incorrect
