Receptors that respond to changes in temperature are called
Correct answer: A. photoreceptors
- A. photoreceptors
- B. thermoreceptors
- C. chemoreceptors
- D. mechanoreceptors
Explanation
Thermoreceptors in the skin and hypothalamus detect heat and cold and feed the thermoregulatory centre. Photoreceptors respond to light, chemoreceptors to chemicals and mechanoreceptors to pressure and touch, so each stimulus has its own receptor family.

About Receptors
Receptors are specialized cells or proteins that detect stimuli such as light, sound, pressure, temperature and chemicals, then initiate responses through sensory or hormonal pathways. Questions distinguish sensory receptors from effectors, compare receptor types, and examine stimulus conversion into nerve impulses, including the roles of rods, cones, chemoreceptors and mechanoreceptors.
