Sensory cells and sensory neurons allow multicellular animals to sense physical and chemical cues from their environment. what key properties of these cells enable them to perform this function? (select all that apply.)

Sensory cells helps in recognizing the outside and inside stimulus. Sensory neurons is one of the most important neurons that transmit the nerve impulse from the sensory receptor to the brain or spinal cord.

Both the sensory neurons and sensory cells have the channel protein receptors. These receptors are linked to the signaling pathways and changes the ion channels permeability. The sensory neurons and sensory receptors have the excitability properties. They changes the membrane potential after binding with the signalling molecules.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
