Zeotropism is a phenomenon observed in certain plants where the direction of growth of a stem or root is influenced by the presence of another plant. This type of tropism is particularly notable in the interaction between a host plant and a parasitic plant. The parasitic plant, known as a hemiparasite, derives some of its nutrients from the host plant while also providing some benefits, such as shade or protection, to the host. The growth of the parasitic plant's roots is typically directed towards the host plant, while the growth of the host plant's roots is often inhibited or redirected away from the parasitic plant. This mutualistic relationship allows both plants to coexist and even thrive in certain environments. Zeotropism is a fascinating example of plant-plant interaction and has been studied in various species, including the mistletoe and its host trees.
