There are two basic ways that individual molecules can enter (or leave) a cell.
1. Diffusion. This is the movement of particles from a region of high concentration to a region of low concentration. So if the concentration of the molecule is higher outside the cell it can enter by diffusion. However diffusion can only take place down a concentration gradient ie from a high to a low concentration.
2. Active transport. This is the movement of particles against their concentration gradient (ie from a low to a high concentration), using energy provided by the cell (ie ATP produced by respiration). So if a molecule is at a higher concentration inside the cell it can only be absorbed by active transport.

When the concentration of water molecules outside the cell is lower than inside the cell water will?
When the concentration of water molecules outside the cell is lower than inside the cell, water will move out of the cell through osmosis. This occurs because water tends to flow from areas of higher concentration to areas of lower concentration. As a result, the cell may shrink or undergo plasmolysis as it loses water.
When the concentration is higher on the outside of the cell it is?
When the concentration is higher on the outside of the cell, it creates a concentration gradient that drives passive transport processes like diffusion and osmosis. This gradient allows molecules or ions to move from an area of higher concentration to an area of lower concentration, resulting in the equalization of concentrations inside and outside the cell.
If substance A could defuse across the membrane what would happen to the concentration of A inside the cell and outside the cell?
If substance A can diffuse across the membrane, it will move from an area of higher concentration to an area of lower concentration until equilibrium is reached. This means that the concentration of A inside the cell will increase while the concentration outside the cell will decrease, assuming that the initial concentration outside the cell is higher than inside. Eventually, the concentrations inside and outside the cell will become equal if no other factors interfere.
What would happen if the concentration of molecules outside the cell was lower than the inside?
the carbon dioxide will move into the cell due to the concentration of carbon dioxide outside of the cell being higher
When do Hemolysis occurs when a blood cell is placed into?
A hypotonic solution. The concentration of solute inside the cell is greater than that outside the cell and water enters the cell by osmosis. Water travels from an area of higher water concentration (outside the cell) to an area of lower water concentration (inside the cell) and the cell swells.
Are lower concentration of water molecules outside the cell normal?
yes!
How does solute concentration affect diffusion osmosis?
Solute concentration affects diffusion and osmosis by creating a concentration gradient. Higher solute concentration outside the cell will cause water to move out of the cell, leading to a decrease in cell volume. Lower solute concentration outside the cell will cause water to move into the cell, increasing its volume.
When the concentration is higher on the outside of the cell it is?
When the concentration is higher on the outside of the cell, it creates a concentration gradient that drives passive transport processes like diffusion and osmosis. This gradient allows molecules or ions to move from an area of higher concentration to an area of lower concentration, resulting in the equalization of concentrations inside and outside the cell.
Is the solution in the hypotonic state transitioning from a low concentration to a high concentration?
No, in a hypotonic solution, the solute concentration is lower outside the cell compared to inside the cell, so the transition is from a high concentration to a low concentration.
What if the solvent concentration is lower outside the cell?
hypertonic
What would happen if the concentration of molecules outside the cell was lower than the inside?
the carbon dioxide will move into the cell due to the concentration of carbon dioxide outside of the cell being higher
What kind of environments causes water to enter or leave the cell?
Water Movement across a cell membrane is called Osmosis. And it is dependent on the concentration of ions on each side of the cell membrane. If the concentration is higher on the inside of the cell water rushes in to dilute the ion concentration and get it to equal the outside concentration of ions and this is called hypotonic. If the concentration is higher outside the cell water will rush out of the cell to help dilute the concentration outside the cell and get the two concentrations to become equal and is called hypertonic. If the concentration is equal in both outside and inside the cell there will be no water movement and is called isotonic. Osmosis
What are the types of solution outside the cell?
The two main types of solutions outside the cell are hypotonic solutions, where the solute concentration is lower outside the cell causing water to move into the cell, and hypertonic solutions, where the solute concentration is higher outside the cell causing water to move out of the cell. These solutions can affect the cell's size and function.
When do Hemolysis occurs when a blood cell is placed into?
A hypotonic solution. The concentration of solute inside the cell is greater than that outside the cell and water enters the cell by osmosis. Water travels from an area of higher water concentration (outside the cell) to an area of lower water concentration (inside the cell) and the cell swells.
How does oxygen cross the plasma membrane if the concentration of oxygen is lower inside the cell than outside the cell?
Oxygen can cross the plasma membrane through passive diffusion, moving from an area of higher concentration (outside the cell) to an area of lower concentration (inside the cell) until equilibrium is reached. This process does not require energy and occurs due to the difference in oxygen concentrations between the cell's interior and exterior.
Based on diffusion what will happen to the substances inside and outside of the cell?
Substances will move from an area of high concentration to an area of low concentration in order to achieve equilibrium. Inside the cell, substances will diffuse out if the concentration outside is higher, and substances will diffuse in if the concentration outside is lower, until equilibrium is reached.
What is the difference in chloride concentration inside and outside the cell?
The chloride concentration is higher outside the cell than inside the cell.
