What part of the cell involves osmosis?
Osmosis primarily occurs in the cell membrane, which is selectively permeable, allowing water molecules to move across the membrane to maintain the cell's internal balance of solutes. Osmosis is crucial for maintaining proper hydration levels and regulating the concentration of solutes inside the cell.
What part of the cell does osmosis occur?
it occurs in the cell membrane(through the cell membrane really)
Are solutes always able to diffuse through a cell's selective permeable membrane?
No, solutes are not always able to diffuse through a cell's selectively permeable membrane. The ability for solutes to diffuse across a membrane depends on the size, charge, and concentration gradient of the solute. Larger or charged molecules may require the assistance of specialized transport proteins to cross the membrane.
What will influence the concentration of water and solutes in the internal environment of a cell?
Factors such as osmotic pressure, active transport mechanisms, and selective permeability of the cell membrane can influence the concentration of water and solutes in the internal environment of a cell. Additionally, external factors like the concentration of solutes in the surrounding environment can also impact the balance of water and solutes inside the cell.
When will water and solutes stop moving across a membrane?
Particles in a given medium stop moving across the membrane during diffusion when a state of equilibrium is reached, that is when the number of particles on either side of the membrane equalizes.

The classes of membrane proteins that permit water and solutes to bypass the lipid portion of the cell membrane are?
The classes of membrane proteins that allow water and solutes to bypass the lipid bilayer of the cell membrane are known as channel proteins and carrier proteins. Channel proteins form pores or channels that allow specific ions or molecules to pass through, while carrier proteins bind to specific solutes and undergo a conformational change to transport them across the membrane.
Is water hypotonic, hypertonic, or isotonic in relation to the cell membrane?
Water is hypotonic in relation to the cell membrane, meaning that it has a lower concentration of solutes compared to the inside of the cell.
What cell membrane have?
Eukaryotes have membrane bound organelles. But not all organelles are bound by a membrane, for example free ribosomes.

Factors such as osmotic pressure, active transport mechanisms, and selective permeability of the cell membrane can influence the concentration of water and solutes in the internal environment of a cell. Additionally, external factors like the concentration of solutes in the surrounding environment can also impact the balance of water and solutes inside the cell.
What does diffusion across the cell membrane cause?
A change in concentration of solutes on either side of the membrane. Depending on the tonicity of the inner-membrane and the outside of the membrane, plasmolysis or cytolysis may occur.
When will water and solutes stop moving across a membrane?
Particles in a given medium stop moving across the membrane during diffusion when a state of equilibrium is reached, that is when the number of particles on either side of the membrane equalizes.
Why would res blood cells burst if you placed them in pure water?
Naturally, solutes, like humans, hate to be crowded and like to have their own space. If given the opportunity, the solutes floating around in red blood cells would move through the cell membrane and float around freely outside. However, since the membrane is impermeable, the solutes draw water in. When too much water is drawn into the cell, the cell bursts. This wouldn't be a problem if the surrounding water wasn't distilled and had a lot of solutes of its own. Then the solutes in the surrounding water would compete with the solutes in the red blood cell to pull water.
What is the process of water diffusing across a what membrane?
Water diffuses across a cell membrane through a process called osmosis. Osmosis is the movement of water molecules from an area of high water concentration to an area of lower water concentration, driven by the concentration gradient of solutes across the membrane. This process helps maintain the cell's internal environment and balance the concentration of solutes inside and outside the cell.
Is the cell membrane a solute?
No, the cell membrane is not a solute. It is a structural component of cells, primarily composed of a phospholipid bilayer with embedded proteins, cholesterol, and carbohydrates. Solutes are substances that are dissolved in a solvent, typically forming a solution, while the cell membrane serves as a barrier and regulator for the movement of substances in and out of the cell.
