Question:
I am working on a biology project dealing with Cell to Cell interactions in Humans.

Through all of my reading and research, I can not pull one aspect of the report together. I know that cell communication deals with the way cells respond to signals coming form outside the cells. What I want to know is if the amount of water in the cell has a vital relationship to the efficiency and ability of cell communication, or does it primarily revolve around the chemical communication (i.e. hormones)?

If you could help I would greatly appreciate it, Thanks!



Replies:
The role of water is primarily that of being the media that the chemicals are dissolved in and transported within. The amount of water has not been determined to have anything to do directly with cell to cell communication. Cells have to rely on a fairly constant amount of water to maintain the osmotic pressure and the amount of dissolved solutes within the cytosol.

Diffusion, endocytosis, phagocytosis and active transport are the main agents of molecular movement.

I hope this is what you are asking.
