WebJul 16, 2024 · These cells are rod shaped and sensitive to light. Although more sensitive to light than cone cells are, rods can not tell what color something is. tissue: Made of cells, it is any of the distinct types of materials that make up animals, plants or fungi. Cells within a tissue work as a unit to perform a particular function in living organisms. 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. boat deck shower
