WebCones have greater acuity and rods have lower acuity. Cones connected singly to bipolar cells so brain receives nerve impulses from small area. Rods have a lower acuity because they are connected in groups, to bipolar cells. Rods have higher sensitivity because they are connected in groups (summation). This is called convergence.
