Is it possible for you to find out whether a plant has taproot or fibrous roots by looking at the impression of its leaf on a sheet of paper?

Answer:

Yes, we can find out the type of root by looking at the impression of its leaf on a sheet of paper. Put paper on the leaf, hold the pencil tip sideways and rub it on the portion of paper having leaf below. We get impression of leaf with some lines on it. If the leaf has parallel venation, the fibrous roots are present in plant and if the leaf has reticulate venation, the tap roots are present in plant.
