NCERT based Answer for Class 11 Biology Students
Mechanism of vision:
Photo pigments are composed of opsin (protein) and retinal (an aldehyde of vitamin A).
Light induces dissociation of retinal from opsin.
This change generates action potential in photoreceptor cells.
Nerve impulse travels through bipolar cells and ganglionic cells and optic nerve and reach visual area in brain (in occipital lobe of cerebrum).
