How does the cell membrane know when to transport water and materials into and out of the cell?

It doesn't! it just lets some materials that are useful for the cells into the membrane and others out, through diffusion.

Structure regulates the transport in and out of the cell?
The golgi bodies regulate the transport of materials in and out of the cell.
What type of active transport brings materials into the cell?
Cell membrane pump
What controls the materials going in and out of a cell?
The Cell Membrane Makes Sure that the materials going in and out of the cell are not harmful, such as a virus.
Regulates the transport of materials in and out of the cell?
cell membrane!! this is the correct answer to number 20... :D
What moves materials in a cell membrane without using energy?
Passive transport is the process in which dissolved materials move across a cell membrane without using a cell's energy.
What is the organelle that works to process and transport materials within the cell and to the outside of the cell called?
cell membrane
The movement of materials through a cell membrane without using the cells energy?
It's called passive transport for a cell's membrane. (I checked with my science teacher)
How does the cell transport materials across the cell membrane?
a cell transports things across the cell membrane from areas of high concentration to ares of low concentration
What is the process by which materials enter and leave the cell through the cell membrane?
Either active transport, passive transport, or facilitated diffusion
What would happen if materials could not move across the cell membrane?
Isolation. And most materials can NOT move across the cell membrane. (For many things your cells have special proteins within the membrane for transport.)
The movement of substances across the cell membrane that requires the cell to use energy?
It's called active transport. When talking about the cell, it is usually bigger substances that use passages in the cell membrane to access the inner part of the cell, and they need energy to get there. The opposite; passive transport or diffusion, is the movement of dissolved materials through a cell membrane without the use of cellular energy. THis happens with smaller substances.
What process require ATP energy to transport materials across a selectively premeable membrane into the cell?
active transport
