Simple Physics May Limit the Size of Leaves

5by Adrian Cho

ScienceNOW – Leaf growth may not be as complicated as it seems. When compared, species to species, shorter trees exhibit a greater variety of leaf sizes than taller ones, with the tallest trees all having leaves that measure 10 to 20 centimeters in length, a biophysicist and a biologist report. The narrow size range may have a simple explanation in the inner plumbing of trees, they say. If it’s correct, the analysis would also explain why the tallest trees top out at about 100 meters.
