they are called receptors.

The function of receptors is to check about the taste,smell,etc. In our human body there are two types of receptors and they are gustatory receptors and olfactory receptors where as gustatory receptors will detect taste and olfactory receptors will detect smell.
one-celled organisms like amoebas don't "see" they detect changes in their environment
dendrites
Sensory (afferent) neurons
The special cells of the sense organs that receive stimuli from the environment are called receptors. The receptors detect different changes in the surrounding envronment and stimulate the neurons to perform the proper tasks.
This ability is known as Weber's Law, which states that the smallest change in a stimulus that can be detected is proportional to the magnitude of the original stimulus. The law suggests that the ability to detect changes in stimuli depends on the intensity or strength of the original stimulus.

Auditory sensory neurons are specialized to detect stimuli from the environment which triggers the neuron to transmit a message to the central nervous system. These stimuli are both voluntary and involuntary.
They are nerves. These nerves tell us exactly what we feel, and then send that information to the brain.
Animals are able to detect changes in their surroundings so that they can defend themselves if there are predators. Additionally, being able to detect changes allows animals to know when to begin hibernating.
Chemoreceptores can detect chemical stimuli.
