(i) Tap root: Tap root consist of a main root, which grows vertically downwards. This main root gives rise to many small branches. They can be observed in the young plantlets of gram.
(ii) Fibrous root: Fibrous root arises in clusters from the base of the stem. They do not have a main root. They can be easily observed in the weeds uprooted for the above activity.
It is important to note that plants with tap roots will always have leaves with reticulate venation, while plants with fibrous roots will always have leaves with parallel venation.
Using this information, one can predict the type of roots a plant has by looking at its leaves.
