Aplant cell remains unchanged in shape or size when it is kept in a solution. what kind of solution is it? a) distilled water b) isotonic solution c) hypotonic solution d) hypertonic solution

Option: "B".

Explanation:

A plant cell remains unchanged in shape or size when it is kept in isotonic solution.

Isotonic solution is the solution having same physical conditions, same osmotic pressure outside and inside the cell.

Osmotic pressure of isotonic solution allows equal movement of cell components from inside the cell to outside of the cell through semi permeable membrane to maintain the state of equilibrium.

Hence, plant cell remains unchanged in isotonic solution.

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
