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.
The cell membrane controls water balance through a process called osmosis. Osmosis is the movement of water molecules across the membrane from an area of lower solute concentration to an area of higher solute concentration. This helps maintain the cell's internal environment and prevent it from bursting or shriveling due to too much or too little water.
Osmosis. If a cell has a lower concentration of solute than water, it is a hypotonic solution and will gain water through osmosis. A hypertonic solution is the opposite. When everything is balanced inside the cell it is called an isotonic solution.

In which organelle does osmosis occur?
Osmosis occurs in the cell membrane of a cell. It is the movement of water across the cell membrane, which controls the balance of water inside and outside of the cell.
What feature of cell prevents water from entering the cell?
Phospholipids in the cell membrane prevent water from entering a cell.
Is the cell-membrane permeable?
Yes, the cell membrane is selectively permeable, meaning it allows certain substances to pass through while restricting others. This allows the cell to control the movement of molecules in and out of the cell to maintain internal balance and regulate cellular processes.
What allows water to cross the permeable membrane of an animal cell?
Water crosses the permeable membrane of an animal cell through a process called osmosis. Osmosis is the movement of water from an area of high concentration to an area of low concentration, across a selectively permeable membrane. This process helps maintain the balance of water inside and outside the cell.
Why do cells control osmosis?
Cells control osmosis to maintain proper water balance and prevent swelling or shrinking. By regulating the movement of water through the cell membrane, cells can ensure that the internal environment stays stable and functions optimally. This process helps to maintain cell shape and prevent damage.

What will disrupt water balance within a single celled organism?
Variations in external osmolarity can disrupt water balance in single-celled organisms by causing water to move into or out of the cell, leading to either cell lysis or dehydration. Changes in ion concentrations like sodium or potassium can also disrupt water balance by affecting osmotic gradients.
What two organelles function in the regulation of water within a cell?
The two organelles that function in the regulation of water within a cell are the cell membrane and the vacuole. The cell membrane controls the movement of water into and out of the cell, while the vacuole helps maintain water balance by storing and releasing water as needed.
Where is the cell control center and the cell membrane?
The cell control center, or nucleus, is typically located in the center of the cell. The cell membrane, which surrounds the cell and controls the entry and exit of substances, is located on the outer boundary of the cell.
The phosphate is water loving but the lipids are not. How will the water enter the cell now?
Water can enter the cell through specialized channels called aquaporins that allow water molecules to pass through the cell membrane. Aquaporins facilitate the movement of water across the lipid bilayer, bypassing the hydrophobic core of the membrane. This enables water to cross the membrane and enter the cell despite the hydrophobic nature of the lipid bilayer.
What feature of cell prevents water from entering the cell?
Phospholipids in the cell membrane prevent water from entering a cell.
Is the cell-membrane permeable?
Yes, the cell membrane is selectively permeable, meaning it allows certain substances to pass through while restricting others. This allows the cell to control the movement of molecules in and out of the cell to maintain internal balance and regulate cellular processes.
What structure regulates the movement of water into and out f a cell?
Cell membrane, specifically aquaporin proteins, regulate the movement of water into and out of the cell through a process called osmosis. These proteins create channels that selectively allow water molecules to pass through, maintaining proper water balance in the cell.

Water crosses the permeable membrane of an animal cell through a process called osmosis. Osmosis is the movement of water from an area of high concentration to an area of low concentration, across a selectively permeable membrane.

What the function of cell membrane in a cell?
The function of the cell membrane is to control what enters and leaves the cell.
