Other types of roots
Besides the more usual roots named above, we should consider those ones that are a bit special. Those not inserted into the soil, either because they are in the open air or because they live inside the water. These special roots are the following:
Those who grow from a stem and are used by some plants to spread along the surface of the soil.
Those living in the water.
They are stuck on another plant, sucking the nutrients from it.The mistletoe is a clear example of this type.
