The eye is an organ of the nervous system. To determine the answer, you can think about the function and structure of the eye. The eye receives visual signals, processes them, and sends images to the brain, which is a characteristic of the nervous system.
In terms of the purpose of the eye, it receives and processes visual signals. To answer this question, you can recall that the eye is responsible for vision and the processing of visual information.
The purpose of photoreceptors is to receive light and turn it into an image. This can be inferred by understanding that photoreceptors are the cells in the retina that detect light and convert it into electrical signals that are then transmitted to the brain.
The eye is an organ, which is a higher organizational level than cells and tissues. To answer this question, you can consider the hierarchical structure of the body, starting from cells, then tissues, organs, and organ systems.
Finally, many parts of the eye work to focus or control light, but the retina is not involved in that process. This can be recognized by understanding the roles of each part of the eye - the lens helps to focus light, the cornea helps to control the entry of light, and the pupil helps to regulate the amount of light entering the eye. The retina, on the other hand, contains the photoreceptor cells and is responsible for detecting and processing light.
