Question

Which means of communication between cells is mostly used by multicellular organisms and why? Give any two reasons.​

Answer 1

Answer:

In multicellular organisms, cell signaling allows for specialization of groups of cells. Multiple cell types can then join together to form tissues such as muscle, blood, and brain tissue.

Answer 2

In most multicellular organisms, chemical communication between cells is preferable to electrical impulses as a way of cell-to-cell communication because

• It involves hormone communication and 2) it doesn't require specialized tissue like nerve tissues for signaling to occur.
• Chemical coordination can occur anywhere in the body, whereas electrical communication is only possible between areas that are connected by nerves.
• While nervous system coordination can only be done intermittently, chemical communication can be done gradually and persistently.
• The benefit of chemical coordination is that information is disseminated throughout the body by blood (then picked up by the necessary part according to its requirements), and the effect typically lasts longer.
