Answer» There are 3 types of communication between the cell- 1.Autocrine signalling- in this signalling the CELLS are nearer to each other and send and receive their signal through the pores on the surface. 2. Paracrine signalling- In this signalling both the cells are at a distance from each other so the signalling molecules reach the RECIEVE site by diffusing through the BLOOD. 3. Endocrine Signalling- in this signalling both the cells are at a LARGE distances so to receive signals, signal molecule pass to RECIEVING site through blood stream.
