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.

What method of molecular transport says water concentration inside a cell is higher than the water concentration outside the cell water flows out of the cell?
Osmosis.
A solution in which the salt concentration inside the cell is higher than outside the cell is known as?
hypertonic :D
Which ions electrical charges oppose the direction of movement that is caused by their concentration gradient?
Positive ions, such as sodium and potassium, have electrical charges that oppose the direction of movement caused by their concentration gradient. This is because they are attracted to the negatively charged side of the plasma membrane, creating an electrical gradient that resists their movement.
What best describes the Na and K concentrations across a neuron's plasma membrane?
The Na concentration is higher outside of the neuron's plasma membrane, while the K concentration is higher inside the neuron's plasma membrane. This creates an electrochemical gradient that allows for the generation and transmission of electrical signals in neurons.
There is a greater concentration of na plus and there is a greater concentration of k plus in the cell?
This describes the ionic distribution across the cell membrane, where sodium (Na+) concentration is higher outside the cell and potassium (K+) concentration is higher inside the cell. This gradient is maintained by the sodium-potassium pump, a vital mechanism for cell function including nerve impulse transmission.
The inside of cells have a higher concentration of what?
The inside of cells have a higher concentration of potassium ions compared to the outside of the cell. This concentration gradient is maintained through the action of ion channels and pumps in the cell membrane.
Will osmosis cause thisIf the concentration of glucose in the water outside of a cell is higher than the concentration inside?
Yes, if the concentration of glucose outside the cell is higher, water will move into the cell by osmosis. This is because water will flow from an area of low solute concentration (inside the cell) to an area of high solute concentration (outside the cell) to equalize the concentrations.
What kind of environments causes water to enter or leave the cell?
Hypotonic environments cause water to enter the cell due to lower solute concentration outside the cell, while hypertonic environments cause water to leave the cell due to higher solute concentration outside the cell.
What is the cell process called when a higher concentration of substance is outside the cell?
Exo-osmosis
How does osmosis change the shape of a cell?
Osmosis can cause a cell to swell or shrink depending on the concentration of solutes inside and outside the cell. If the concentration of solutes is higher outside the cell, water will move into the cell, causing it to swell. Conversely, if the concentration of solutes is higher inside the cell, water will move out, causing the cell to shrink.
The concentration of material is greater on the outside of the cell than the inside in what solution?
The concentration of material is greater on the outside of the cell than the inside in a hypertonic solution. In this solution, there is a higher concentration of solutes outside the cell compared to inside, causing water to move out of the cell, leading to cell shrinkage.
When is a substance most likely to diffuse into a cell?
If there is the concentration of substance inside the cell is lesser than outside and cell membrane is permeable to the substance.
What method of molecular transport says water concentration inside a cell is higher than the water concentration outside the cell water flows out of the cell?
Osmosis.
What substance enters and leaves a plant cell through the process of osmosis?
Water enters and leaves a plant cell through the process of osmosis. When the concentration of water inside the cell is higher than outside, water will move into the cell, and when the concentration is higher outside, water will leave the cell.
A solution in which the salt concentration inside the cell is higher than outside the cell is known as?
hypertonic :D
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.
What role did diffusion play in the changes you observed?
Before diffusion there is a higher concentration of oxygen molecules outside the cell than inside the cell. After diffusion the concentration of oxygen molecules is the same outside and inside the cell.
