Life scientists from UCLA’s College of Letters and Science have discovered fundamental rules of leaf design that underlie plants’ ability to produce leaves that vary enormously in size. In their mathematical design, leaves are the “perfect machines,” said Lawren Sack, a professor of ecology and evolutionary biology and senior author of the research.
The UCLA team discovered the mathematical relationships using “allometric analysis,” which looks at how the proportions of parts of an organism change with differences in total size. This approach has been used by scientists since Galileo but had never before been applied to the interior of leaves. (more…)
