Land plants evolved 470 million years ago from algae and have since reshaped our world. Throughout their evolution, ferns have undergone a series of changes that have helped them survive on land. For ...

Plant biologists report that a species of tree fern found only in Panama reanimates its own dead leaf fronds, converting them into root structures that feed the mother plant. The fern, Cyathea ...

During photosynthesis, trees convert the carbon dioxide to sugars and in doing so produce oxygen as a biproduct, which is vital for life on Earth. “Trees draw carbon dioxide out of the atmosphere and ...
