does the green leaf of a plant stay cooler in the sun than a similarly shaped/colored object? i.e. does the photosynthesis that happens in a plant's leaf noticeably reduce the amount of solar energy that gets converted to heat?
also, anyone know the quantum efficiency of a chloroplast cell/organelle/whatever the hell is it?

Cooler yes, but not only through photosynthesis. Leaves are living things so they evaporate some water to cool off as well just like mammals sweat. The efficiency of photosynthesis is not very good and it depends on amounts of water, oxigen, carbon dioxide and other metabolic agents. Different plants also grow at different rates.

Why does each man or woman assume that Atheist= Darwinist? possibly there are atheists obtainable who don't think in technological understanding, both. Ever imagine of that, smart guy? besides, once you've any theory what evolution is about, then you honestly'd comprehend that flora did not commence out as flora. they did not only faster or later come out of the floor completely formed with photosynthesis already loaded like a utility. it is a few thing that replaced and developed over the years even as different technique of survival diminished out (in idea, recommendations you). after all, there are distinctive complicated methods that bypass on in flora and animals that are only as confounding to undemanding factors. Why no longer %. fish reproduction, or mammalian milk production?

the green plant keep cooler cuz of transpiration (water leave the leave throught stomata in the morning ) so the water absorb energy to be trasfared to vapour so the leaf be cooler and the leave contain chlorophly A,B in the chlorplasts responsible for absorbing sun light to be used in photosynthesis so this energy is storded and released in reduction to co2 to produce carboydrates (( light and dark reactions)) so like that light solar energy is used

Sorry I can't actually answer (GREAT question -- it seems to me they would be, as they are using the energy), but you might consider posting this on an Ask the Scientists site.
I know of one: New Scientist-- it's a UK science publication with a web site. It's possible someone's asked already, you may want to search or browse an appropriate category. (Which I'll do now, myself.)

Don't know, great question tho.
