Solution
Structure of taste buds: There are four primary tastes-sweet, salty, sour, and bitter. The taste receptors are called taste buds. Each taste bud opens on the tongue surface through a taste pore. Each taste buds contains 60-65 spindle-shaped cells, out of which 5-15 are taste receptor cells and other supporting cells. The taste receptor cells produce protoplasmic outgrowths called taste hair. The taste hair project through taste pore and receive the stimulus of taste.
| Taste buds | Location |
| Sweet | Front of the tongue |
| Salt | Tip and sides of the tongue |
| Bitter | Rear |
| Sour | Back and sides of the tongue |
