Which one of these is Not an example of intercellular communication

A. Energy production

B. Signaling molecule diffuses through Plasmodesmata morning of plant

C. Nerve signal transmitted from brain cell to skin cell

D. Pituitary hormone regulates body temperature

The correct answer is option A, " Energy production"

Reason:

The intracellular communication is the process through which one cell interacts with other cell for proper functioning of the body. The two major types of intracellular interaction involve:

a) Chemical Synapse - In this a chemical released by one cell is detected by receptor on another cell. For example the transmission of sodium and potassium ion across the membrane through the binding of Acetylcholine (Ach) with ACh receptors.

b) Electrical Synapse - In this the cell which are connected through non selective, low - resistance pore between pre - and postsynaptic neurons known as gap junction.

This is the case in option B, C and D.
