Knöllchen vs Wurzel
root
'die Wurzel' and 'das Knöllchen' can both occur underground on a plant. However, 'Wurzel' means the part that holds the plant in place and absorbs water. 'Knöllchen' is a small tuber, meaning a thickened plant part that stores nutrients. Learners may confuse the words because both are in the soil. If you are speaking generally about the lower part of a plant, 'Wurzel' fits. If you mean a small, round, or thickened storage part, 'Knöllchen' fits.
