What is relationship between osmosis and diffusion?
The relationship is that osmosis is the diffusion of water throught a selective permeable membrane.
How can a door greeter relate to a cell membrane?
a cell membrane is semi-permeable. meaning that it selectively chooses between what can go in and out of the cell. A door greeter is similar to this because a door greeter can tell who to allow in/out of the building they are in.
What is the Simlilarity between osmosis and reverse osmosis?
1) They both require the presence of a differentially/selectively permeable membrane/tubing. 2) They both refers to the flow of water(ONLY WATER!!!) through a differentially/selectively permeable membrane/tubing . 3) They both require energy. - They both cannot at -273.15 degree Celsius. 4) They will both reach a equilibrium and eventually stop.
Does the plasma membrane of a living cell form an impenetrable barrier between the internal millieu and the environment?
No, the plasma membrane is a selectively permeable barrier that regulates the flow of most molecules across the membrane. The plasma membrane allows waste products to exit the cell and nutrients to enter the cell.
What is the main fuction of the plasma membrane?
The main function of plasma membrane is to regulate things in or out of the cell cytoplasm by osmosis,active diffusion,passive diffusion,endocytosis,ectocytosis etc because it acts as selectively permeable membrane.Plasma membrane forms a barrier between the interstitial fluid and inside cell environment. It is selectively permeable. Plasma membrane has trans membrane proteins embedded in it.
Where is the net movement of water in a hypotonic solution?
no Water will move freely between the two solutions if they are separated by a selectively permeable membrane. However, there will be no net change in the concentration of water on either side of the membrane. Differences in solute concentration will allow you to predict net changes in water movement.
What is the difference between colloid and crystalloid?
The particles which passes through semi permeable membrane are called crystalloid. and the particles which doesn't pass through semi permeable membrane are called colloids.
What is the difference between a semi-permeable and a partially permeable membrane?
An impermeable membrane is that through which no substance can pass. Semipermeable membranes are those that let only solvents, like water, to pass through it. Permeable membranes are those that let solvent and solutes, like ions and molecules, to pass across it. There are also selectively permeable membranes, i.e., membranes that besides allowing the passage of solvent, let only some specific solutes to pass while blocking others. See link:
What fills the space between cell wall and membrane after plasmolysis?
The cell membrane is a selectively permeable membrane that will only let water and solutes across it. The cell membrane freely allows pretty much everything to pass across it, meaning that things unable to pass the membrane back up and push it away from the cell wall. Therefore the gap is filled with the SUGAR SOLUTION that is surrounding the cell.
What is the difference between selectively and semi permeable?
The difference is that semipermeable only lets in and lets out molecules small enough to fit through. Selectively permeable has channel proteins that allow bigger molecules to fit through.*Added info*Semipermeable:Matter of sizeWhat fits in goes through, what does not stays out.Like a filterSelectively permeable Small or big can go in as long as they are selected.Ex. food in, bad bacteria stay out
What term describes the difference between the numbers of hydrogen ions on opposite sides of the membrane?
Diffusion and it does not have to be through a semi permeable membrane.
What is a semi-permeable membrane that forms a boundary between the cell and the external environment?
The cell membrane is a semi-permeable membrane that forms a boundary between the cell and the external environment. The vacuole is the storage area within the cell.
