Verified step by step guidance

Begin by understanding the structure of the eye and the function of its components. The eye is composed of several parts, including the cornea, lens, retina, rods, and cones.

Focus on the retina, which is the layer at the back of the eye responsible for receiving light and converting it into neural signals. The retina contains two types of photoreceptor cells: rods and cones.

Learn about the function of rods and cones. Rods are responsible for vision in low light conditions and contain the pigment rhodopsin, which is sensitive to light. Cones are responsible for color vision and function best in bright light.

Understand the role of rhodopsin. Rhodopsin is a light-sensitive pigment found in the rods. It plays a crucial role in the phototransduction process, which is the conversion of light into electrical signals in the retina.

Conclude that the part of the eye that can sense light with the help of rhodopsin is the rods, as they contain this pigment and are specialized for detecting light in dim conditions.
