Callus is a botany term, it is a tissue that
forms at a damaged plant surface. Composed of
large, thin-walled parenchyma cells, it grows
over and around the wound, eventually
covering the exposed area. In animals, a
callus is a thickened pad of skin, formed
where there is repeated rubbing against a
hard surface. In humans, calluses often
develop on the hands and feet of those
involved in heavy manual work.
