Question

ii) a) By which cells the retina in human eye is made up of ?
b) Which cells respond to the intensity of light?
c) Which cells respond to the colour ?
d) Which perons are unable to distinguish between different colour
e) Why one can sense colours only in bright light?​

Answer 1

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.

Rod cells in the retina respond to the intensity of the light.

The cells that respond to colour are cones and the cells that respond to intensity of light are rods.

Colour-blind persons are unable to distinguish between different colours.

Because we, the humans have a grear percent of rod cells in our retina which are sensitive in bright light. Cones are small photo receptors present inside the eyes. They are responsible for the color detection and help us see different colors.

Hope this helps

Answer 2

Explanation:

i). the retina, five types of neuron — photoreceptors, bipolar cells, retinal ganglion cells, horizontal cells and amacrine cells

ii). rod cell

iii) cones cell

iv color blind person

v). The cells present on the retain and responsible for colour vision are known as cone cells. These cells become active only under bright light and remain inactive under dark. Thus, we are able sense only in bright light.
