From UC Davis California
Redwoods have two types of leaves, one to make food and the other to absorb water
Study is first to estimate whole-crown water absorption in a large, mature tree
Leaf types shift places on the tree depending on if environment is wet or dry
Findings can help scientists monitor trees’ adaptability amid a changing climate
Redwoods are among the most well-studied trees on the planet, and yet their mysteries continue to surprise and delight scientists and nature lovers.
Scientists from the University of California, Davis, discovered that redwood trees have two types of leaves, and those leaves have completely different jobs, according to a study in the American Journal of Botany. Together, these functionally distinct leaves allow the world’s tallest trees to thrive in both wet and dry parts of their range in California, without sacrificing water or food.
