Explanation:
Detailed explanation-1: -The retinal is the principal molecule of vision in the retina. It can absorb different frequencies of light.
Detailed explanation-2: -Photoreceptors are specialized neurons found in the retina that convert light into electrical signals that stimulate physiological processes.
Detailed explanation-3: -The great biological importance of photoreceptors is that they convert light (visible electromagnetic radiation) into signals that can stimulate biological processes. To be more specific, photoreceptor proteins in the cell absorb photons, triggering a change in the cell’s membrane potential.
