Question

Some plants have roots present abpve the ground. So how can we consider them as roots as the definition of roots is part of plant below the soil

Answer 1

Plants have three types of root systems: 1.) taproot, with a main taproot that is larger and grows faster than the branch roots; 2.) fibrous, with all roots about the same size; 3.) adventitious, roots that form on any plant part other than the roots.In vascular plants, the root is the organ of a plant that typically lies below the surface of the soil. Roots can also be aerial or aerating, that is, growing upabove the ground or especially abovewater. However, important internal structural differences between stemsand roots exist.
