How is the organ of prehension identified for a cow?

The organ of prehension in a cow is identified as the tongue because it plays a crucial role in grasping and manipulating food. Cows have evolved a long, agile tongue that allows them to reach grass and forage effectively, which is essential for their herbivorous diet. The ability of the tongue to wrap around and pull plant material into the mouth is what makes it the primary organ for this purpose in these animals.

While other anatomical features such as the lips, beak, and teeth contribute to feeding, they do not function as the primary means of grasping food. The tongue’s unique structure and motor capability make it particularly suited for the prehension required in grazing and eating, thus clearly establishing it as the correct answer.
