Answer:
Correct Answer: A
Solution:
The chemoreceptor of taste are the taste buds found on papillae of the tongue and on the soft palate.
Each taste bud is a group of elongated spindle shaped receptor cells and supporting cells.
The inner free ends of receptor cells bear fine sensory hairs while their outer ends are supplied by nerve fibers from VIIth and IXth cranial nerves.
Taste buds open by taste pores into depressions between tongue papillae.
The taste buds are sensitive to dissolved substances which stimulate sensations of sweet, sour, bitter, salty etc.
