Leaf size and venation show remarkable diversity across dicotyledons, and are key determinants of plant adaptation in ecosystems past and present. Here we present global scaling relationships of ...

Biologists have discovered fundamental rules for leaf design that underlie the ability of plants to make leaves that vary enormously in size. Life scientists from UCLA's College of Letters and Science ...

Most leaves are green due to the pigment chlorophyll, but other colours, such as oranges, reds and blues, may also be present due to less efficient photosynthetic pigments like anthocyanins, carotenes ...
