Question

1. Communication occurs among the cells in a multicellular organism. Choose THREE of the following examples of cell-to-cell communication, and for each example, describe the communication that occurs and the types of responses that result from this communication. · Communication between two plant cells Communication between two immune-system cells Communication either between a neuron and another neuron, or between a neuron and a muscle cell Communication between a specific endocrine-gland cell and its target cell

Explanation / Answer

Communication between two immune cell system is autocrine signalling where releaser itself is an acceptor. Communication between two neurons or a neuron and a muscle is paracrine signalling where cells that are adjacent to releaser cell only show response and communication between specific endocrine cell and its target cell is endocrine signalling which is a long distance communication and concentration of signal should be very higher. A medium to travel is also required. These three are under cell to cell communication.
