the cell mebrane has achannel espicially for water, in some cases according to the osmolarity around cell mebrane the water will go from high concentration to low concentration by these channels . in this way cell membrane will keep the osmotic pressure equal on both sides by movement the water
What else can I help you with?
How does the structure of the cell's membrane help the cells regulate water?
The semi-permeability of the cell membrane regulate water movement by osmosis.
Can osmosis occur in boiled cells?
No, osmosis cannot occur in boiled cells because boiling denatures the cell membrane and destroys its structure, preventing the movement of water molecules across the membrane. Osmosis requires an intact cell membrane to regulate the movement of water in and out of the cell.
Define the structure and function of the cell membrane plasma membrane?
The cell membrane consists of a lipid bilayer which is actually a phospholipid. Cell membranes are semipermiable and they regulate what enters and leaves the cell.
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.
What role does an integral membrane protein play in the structure and function of a cell membrane?
Integral membrane proteins are embedded within the cell membrane and play a crucial role in maintaining the structure and function of the membrane. They help regulate the passage of molecules in and out of the cell, facilitate cell signaling, and provide structural support to the membrane. Overall, integral membrane proteins are essential for the proper functioning of the cell membrane.
Structure regulates the transport in and out of the cell?
The cell membrane is the structure that regulates the transport of molecules in and out of the cell. It is selectively permeable, allowing certain substances to pass through while restricting others. Transport proteins embedded in the membrane help facilitate the movement of specific molecules across the membrane.
What the animal cell membrane's job?
The animal cell membrane's job is to regulate the passage of substances in and out of the cell, thus controlling the cell's internal environment. It also provides structure and support to the cell.
What structures in a plant cell help regulate the amount of water in a cell?
The chromosomes. this is wrong. the cell membrane is what regulates the amount of water inside the cell.
What attracts water in the cell membrane and how does it contribute to the overall structure and function of the cell?
Water is attracted to the cell membrane due to the presence of hydrophilic (water-attracting) molecules in the membrane. This attraction helps maintain the structure of the cell membrane and allows for the passage of water and other molecules in and out of the cell, which is essential for various cellular functions such as nutrient uptake and waste removal.
Where does the cell membrane exist?
Inside the cell. This is in the far right middle of the cell.
How does the cell membrane structure relate to its function?
The cell membrane is composed of a phospholipid bilayer with embedded proteins that regulate the passage of substances in and out of the cell. This structure allows the cell membrane to be selectively permeable, controlling the movement of molecules and ions. This is crucial for maintaining cellular homeostasis and communication with the external environment.
What might you conclude about the membrane structure of the final vesicle formed during exocytosis and the cell membrane?
The final vesicle formed during exocytosis will have a similar membrane structure to the cell membrane, as it is produced from the cell's internal membrane systems. These membranes are composed of a lipid bilayer with embedded proteins that help regulate transport and signaling. The vesicle membrane will fuse with the cell membrane during exocytosis, allowing the contents to be released outside the cell.
