1.Tap root system arises from radicle of the embryo whereas the adventitious roots arise from any part of the plant body other than radical or its branches .They can arise from stem, leaves etc.
2.In tap root system there is single main root called tap root which bears branches in an acropetal manner .In adventitious roots there are number of equally strong fibrous roots present in clusters.
3.Tap root system is underground whereas adventitious roots may be underground or aerial.
4.In tap root system the primary root or tap root persists throughout life of plant. In adventitious root system the primary root is short lived and is replaced by adventitious roots.
5.Tap root system may be deep feeder or surface feeder whereas adventitious root system is mostly surface feeder.
