Cytoplasm – intercelluar water
So I wanted to know little more about the intercellular water, cytoplasm which is essentially salty water with various organic molecules suspended in it. Here is more about how the water is contained.
The cytoplasm is contained within a cell membrane. Cell membrane is a phospholypid bilayer – this means that it is composed of two layers of tighly packed molecules of fat. Within the membrane, proteins are embedded into the bilipid layer and are more or less free to move around within the membrane. These proteins are important for the communication between the inside and outside of the cell.
