In some barks the cork cambium and cork tissues are laid down in a discontinuous and overlapping manner, resulting in a scaly type of bark (pines and pear trees); in other barks the pattern is continuous and in sheets (paper birch and cherry). Saplings of emergents and canopy trees can also be found here. A type of transfer cell and supplied with many protoplasmic connections to the adjacent root cells, root hairs increase the absorbing area of the roots at minimal carbon cost and can penetrate finer pores in the soil. "As periods of drought begin to be seen more frequently in tropical forests the lungs of our planet the risk that these ecosystems will burn increases," said Coulson, who is familiar with the study but had no role in it. 5 How have plants adapted to the rainforest?
