Here's why:

* Receptor cells are specialized cells that detect stimuli from the environment. These stimuli can be light, sound, touch, taste, smell, temperature, pain, or pressure.

* Sensory organs are structures that house these receptor cells and allow them to effectively detect and transmit sensory information to the nervous system.

Examples of sensory organs include:

* Eyes: Contain photoreceptor cells that detect light.

* Ears: Contain mechanoreceptor cells that detect sound waves.

* Skin: Contains various mechanoreceptors, thermoreceptors, and nociceptors that detect touch, temperature, and pain.

* Tongue: Contains chemoreceptors that detect taste.

* Nose: Contains chemoreceptors that detect smell.
