Parts A, B, C and D of the human eyes are shown in the diagram. Select the option, which gives correct identification along with its functions/characteristics

Options

  1. AA-retina-contains photoreceptors-rods and cones
  2. BB-blind spot-has only a few rods and cones
  3. CC-aqueous chamber-reflects the light, which does not pass through the lens
  4. DD-choroidits anterior part forms ciliary body

Correct answer

A. A-retina-contains photoreceptors-rods and cones

Step-by-step solution

A-Retina-contains photoreceptors - rods and cones. The daylight vision is function of cones and twilight vision is related to rods. B-Blind spot-Phatoreceptor cells are not present in this part. C-Aqueous chamber contains a thin watery fluid called aqueous humour. D-Sclera is the external layer of eye having dense connective tissue.
