Question

On the way home one day, Amit saw a man beating bundles of wheat. He was confused - why is the farmer beating around bundles of wheat? What is this process called? Explain the mechanism.

Answer 1

By beating bundles of wheat, the farmer is trying to free the grain seeds from the stalks and this process is known as threshing.

Grains are attached at the weakest links of the stalk. As bundles of stalks are beaten, grains detach from the stalk and fall apart.
Threshing can be performed manually or with the help of machines.
