Vedclass · Answer

(B) Based on the morphological structure,cell $A$ represents a cone cell,which is characterized by a conical outer segment. Cone cells are highly concentrated in the fovea centralis (yellow spot) of the retina. They are responsible for colour vision and high-resolution vision in bright light. Cell $B$ represents a rod cell,which is characterized by a cylindrical outer segment and is sensitive to low light intensities (scotopic vision) but does not provide colour vision.
