Question

Match the following terms and definitions. 1. chemoreceptors neurons that detect chemicals 2. mechanoreceptors neurons that detect touch 3. olfactory receptors neurons that detect light 4. photoreceptors neurons that detect smells 5. thermoreceptors neurons that detect temperature

Answer 1

Answer: The correct answer is - 3) olfactory receptors neurons that detect smell. 4) photoreceptors neurons that detect light .

1) and 2) statements are correctly matched in the question..

Olfactory receptors are also called odorant receptors. The olfactory receptor neurons detect smell and thus give a sense of smell to the organism. They are present in the nasal cavity.

Photoreceptor neurons are those that detect light and they are present in the retina of eye.
