Answer 1

${\huge{\underline{\underline{\mathcal {\red{♡Answer♡}}}}}}$

★Follow the given function of retina:-

• The retina is the film of the eye like the film of a camera.

• The retina is the light-sensing part of the eye.

• It converts the incident light into electrical signals and sends them to the brain.

Answer 2

Answer:

The neural retina consists of several layers of neurons interconnected by synapses, and is supported by an outer layer of pigmented epithelial cells. The primary light-sensing cells in the retina are the photoreceptor cells, which are of two types: rods and cones. Rods function mainly in dim light and provide black-and-white vision. Cones function in well-lit conditions and are responsible for the perception of colour, as well as high-acuity vision used for tasks such as reading. A third type of light-sensing cell, the photosensitive ganglion cell, is important for entrainment of circadian rhythms and reflexive responses such as the pupillary light reflex.
