Question

The eyes convert light energy into neural responses that we experience as sight. The conversion of light energy into sight is done by receptor cells in the _______.

Answer 1

Answer:

The correct answer is: Retina.

Explanation:

• The Retina can be defined as the fine layer of sensory epithelial tissue located near the backward region of the eye.
• It forms the screen where the image of the object (located outside the eye) is formed after the light from the object gets refracted and focused by the crystalline convex lens in the eye.
• It is located in close vicinity to the Optic Nerve.
• The Retina is lined by specialised light-sensitive photoreceptor cells.
• There are two types of light sensitive-photoreceptor cells which are called the Rods and Cones.
• The Rod cells are responsible for determining the intensity of light.
• The Cone cells are responsible for determining the colour.
• The Retina is responsible for converting the light signal received by the eye into a neural impulse which is then sent to the brain through the optic nerve.
