Answer: The concentration of solutes is the same both inside and outside of the cell : isotonic
The concentration of solutes is less outside the cell than inside the cell : hypotonic
the concentration of solutes is greater outside the cell than inside it: hypertonic
the diffusion of water across a selectively permeable membrane: osmosis
the movement of molecules from a region of high concentration to a region of low concentration by means of random molecular motion : diffusion
a membrane that allows only specific molecules to move into or out of the cell : selectively permeable
Explanation:
The solutions having same osmotic pressure and hence same molar concentration are termed as isotonic.
If a solution is of lower osmotic pressure it is called as hypotonic with respect to the concentrate solution.
The more concentrated solution is said to be hypertonic with respect to the dilute solution.
Osmosis is defined as the process in which molecules of a solvent tend to move through a semipermeable membrane from a region of low concentration solution to a region of more concentrated solution.
Diffusion can be defined as a phenomenon that occurs in liquid or gases which is the process of movement of solute particles from area of high concentration to low concentration.
Selectively permeable membrane is a membrane which allows selective movement of molecules.
Answer:
Diffusion is the process of a substance moving from an area of high concentration to an area of lower concentration. Osmosis is a type of diffusion where water moves across a semipermeable membrane still from an area of high concentration of water to an area of lower concentration of water. This corresponds to water moving from an area with a low concentration of solute to an area with a higher concentration of solute.
A semipermeable membrane allows some substances to pass through it.
The plasma membrane of a cell allows small uncharged molecules to pass through it, but not large molecules and not charged ions.
The protein molecules were evenly distributed on both sides of the membrane, so this solution was isotonic.
In an isotonic solution, water moves both in and out of the cell, which was observed in the simulation.
The protein molecules were more highly concentrated on the inside of the cell, so this solution was hypotonic.
In hypotonic solutions, water moves into the cell to help dissolve the higher amount of solute inside the cell, which was observed in the simulation.
A semipermeable cell membrane is important to allow some molecules, like proteins, to be more highly concentrated inside the cell than outside the cell. If the cell membrane were permeable, the molecules on the inside of the cell would exit the cell and be evenly distributed in the cell and in its environment.
If the cell membrane were not permeable at all, the cell would not be able to receive nutrients from its environment.
