PPT-Cell-to-Cell Communication

Synapse Types Electrical may be directional probably not important computationally Chemical classical model is that they transmit information unidirectionally not strictly correct. By Domonique Harris. BUS 226 Presentation. October 16, 2013. Purpose. Information communicated in our workplace must be communicated correctly and effectively.. . - Ask yourself questions. If you are the sender of the message, ask yourself, “How am I relaying this message?” What is my tone? How is my delivery? Is my message understandable?. Zhang . Junqiu. Paper . presentation. Nature 2004, 428:868-871. Introduction. We want to build a quorum-sensing system which can control cell density at a constant amount autonomously..

Cell membrane is like the doors on a car. They regulate what goes in/out.. The cell wall in a plant cell is like the frame on a car. The frame supports the car as the cell wall supports the plant.. The endoplasmic reticulum is like the fuel lines on a car. It lets a passage way for fuel to flow like proteins do in the endoplasmic reticulum . Cell membrane is like the doors on a car.

In order to properly respond to externals stimuli, cells have developed complex mechanisms of communication that can receive a message, transfer the information across the plasma membrane, and produce changes within the cell in response to the message. The ability of cells to communicate through chemical signals originated in single cells and was essential for the evolution of multicellular organisms.
