B Colour perception in man is due to iodopsin pigment in cone cells. In the retina there are specialized photoreceptor called cones. Three types of cones which respond to red (erythropsin) green (chloropsin) and blue light (cyanopsin). Other colours are detected by simultaneous stimulation of more than one type of cone cell. Iodopsin is responsible for the voilet pigment of cone cell of the retina where as rhodopsin responsible for the visual purple pigment of rods cells.

Which of the following cells are associated with identification of colours in bright light
1 Rod cells
2 Cone cells
3 Both [a] and [b]
4 None of these
Explanation:
B Rod cell and cone cells are the photo receptors present in the human retina. Rod cells are responsible for vision at low level of lights while cones cell are responsible for vision at bright level of lights. They respond differently various wavelengths of light and works betters in bright. Cone cells are responsible for colour vision.

A person suffering from the deficiency of the visual pigment rhodopsin is advised to take more of
1 Radish and potato
2 Apple and grapes
3 Carrot and ripe papaya
4 Guava and ripe banana
Explanation:
C Carrot and ripe papaya contain carotene which is form of vitamin ' ' is synthesized vitamin- is necessary for the formation of rhodopsin. The visual pigment responsible for photo transduction know as rhodopsin. Rhodopsin is found in the rod cell of the retina which are specialized for low light or scotopic vision. Rhodopsin consist of two components such as opsin protein and retinal (a derivative of vitamin A). Rhodopsin is sensitive to low light visual.

In dark adaptation :
1 only cones are involved
2 only rods are involved
3 both rods and cones are involved
4 neither rods nor cones are involved
Explanation:
B In dark adaptation only rods cells are involved. Rod cells are highly sensitive to light and can detect even small amounts of light. Cone cells are responsible for colour perception they contain different type of photo pigments that are sensitive to different part of visible light spectrum.

Part of ear where sound is transduced is :
1 Tympanic membrane
2 Malleus, incus and stapes
3 Semicircular canal
4 Cochlea
Explanation:
D The cochlea represents the hearing part of the inner ear and is situated in the temporal bone. The cochlea is a fluid-filled, spiral shaped cavity found in the inner ear that plays a vital role in the sense of hearing and participates in the process of auditory transduction. Sound waves are transducer into electrical impulses that the brain can interpret as individual sound frequencies.
