Assertion: The pigmented layer of the neurosensory tunic is exclusively present along the ciliary body and iris due to the inability of light rays to reach the ciliary body and the posterior region of the iris for image formation.
Reason: The absence of light penetration towards the ciliary body and the posterior portion of the iris inhibits the formation of an image.
Both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
Both Assertion & Reason are True but Reason is not a correct explanation of the Assertion.
Assertion is True but the Reason is False.
Both Assertion & Reason are false.
Answers (1)
The assertion states that the pigmented layer of the neurosensory tunic is exclusively present along the ciliary body and iris. This means that the layer containing pigment, which is responsible for absorbing excess light and preventing glare, is found only in these specific areas of the eye.
The reason provided for this assertion is that light rays cannot reach the ciliary body and the posterior region of the iris to form an image. This means that the incoming light is unable to penetrate deep into these areas of the eye, hindering the formation of a clear image. The pigmented layer, therefore, plays a role in preventing light from reaching these regions and interfering with vision.
Therefore, option 1 is the correct answer which states that both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
