Osmosis, which is the movement of water across a semi-permeable membrane from where it is in high concentration to where it is in lower concentration. The purpose of osmosis is to equalize the concentration of solutes inside a cell and outside a cell.

How does a cell control what enters and leaves?
The cell membrane enables a cell to control what enters and leaves. The membrane has a selective semi-permeable membrane which facilitate this process.
Why will a cell membrane shrink when placed in salt water?
Salt water is a hypertonic solution; therefore, the vacuole in the cell will shrink. The water in the cell's vacuole exits the plasma membrane to balance the solutions, and since the salt can not enter through the cells differentialy permeable membrane the cell is only loosing substance so it shrinks. When the elodea cells are in fresh water there is no reaction. Elodea is a fresh water plant
What types of molecules can easily go through your cell membrane are permeable to the cell membrane?
Substances with a hydrophillic-lipophillic balance are permeable through the cell membrane.
Which part of a cell controls what gets in and out of the cell?
The plasma membrane / cell surface membrane. The phospholipid bilayer prevents certain substances passing straight through, so protein channels and other mechanisms control what does and does not pass in and out of the cell.
What will the cell membrane will absorb?
The cell membrane will absorb food, water, and oxygen. .
What will disrupt water balance within a single celled organism?
Cell membrane
Where is the cell control center and the cell membrane?
where is the cell control membrane and the cell membrane

In a cell what function of the cell membrane?
The function of the cell membrane is to control what enters and leaves the cell.
What the function of cell membrane in a cell?
The function of the cell membrane is to control what enters and leaves the cell.
What is a function of a cell membrane in all cells?
a cell membrane helps with the process diffusion. the cell membrane allows water to equal out between the outside and inside of the cell. if the cell gets to full of waters it will burst it the cell does not have enough water it will shrivel up. so a membrane is important to keeping the balance in a cell.
The phosphate is water loving but the lipids are not. How will the water enter the cell now?
The cell membrane is designed to keep a balance in the cell. It has a water loving layer, a water hating layer, and a water loving layer. The water loving layer repels fats. The water hating layer repels water. Cells have pores which extend through the cell membrane. The pores control inflow and outflow. The pores control the amount of water in the cell. If the cell does not have enough liquid, they open. If it has to much, they close. These pores need a certain amount of sodium, potassium, and calcium in the blood stream to control them. If your body has too much sodium, the pores in your kidneys have difficulty working and your blood pressure rises. If your body has low sodium, your kidneys might work overtime and deplete the sodium your body has. It is important to keep your electrolytes in balance.
How do living cells with and without cell walls regulate water balance?
Well, water by itself cannot diffuse into the cell easily, because of its polarity. The cell membrane ultimately determines how much water goes in and out of the cell by aquaporins and other channel proteins. Remember, the membrane is selectively permeable.
State how the cell membrane control the passage of substance in and out of cell?
it controls the movement in and out of the cell . examples : water, food, oxygen and wastes
What does the cell membrane in the animal cell do?
The function of the cell membrane is to hold the cell together and control what goes in and out of the cell.
What does the cytoplasm and the cell membrane do?
the cell membrane is an extra layer after the cell wall to control what comes in and out.
