Aerial roots on orchids rapidly absorb water and nutrients

Orchids are a diverse family of plants that includes species adapted to life high above the ground in humid rainforests. These orchids are epiphytes that grow on other plants. To collect water, some epiphytic orchids dangle their roots in the air and absorb moisture directly from the atmosphere, from rain, and from water that drips off vegetation above it. Others spread their roots over the surfaces of tree branches and collect water as it trickles over the tree’s surfaces.
