Answer 2

$\large\rm{ \green{Answer}}$

a) Smell plays any role in identifying taste:-

The sense of smell plays a vital role in finding food, discriminating it from toxic substances, and appreciating its flavor.

b) Foods can be distinguished based on smell:-

Yes, Smell help us to distinguish not only good from bad food but also the good.

c) Foods can be distinguished based on appearance:-

The most important attribute of any food's appearance is its color, especially when it is directly associated with other food-quality attributes, for example the changes that take place during the ripening of fruit or the loss in color quality as food spoils or becomes stale.

d) Sight, smell and taste play any role in digestion:-

Although sight is not technically part of taste, it certainly influences perception. Cells that recognize these flavors reside in taste buds located on the tongue and the roof of the mouth. When food and drink are placed in the mouth, taste cells are activated and we perceive a flavor.

Smell is as important, if not more important, than taste. If this channel is blocked, such as when our noses are stuffed up by a cold or flu, odors cannot reach sensory cells in the nose that are stimulated by smell, so we don't enjoy foods the same way. Without smell, foods tend to taste bland and have no flavor.

Once taste signals are transmitted to the brain, several efferent neural pathways are activated that are important to digestive function. For example, tasting food is followed rapidly by increased salivation and by low level secretory activity in the stomach.
