Osmosis and Diffusion Vocab Flashcard

Front

What is an isotonic solution?

Back

A solution with the SAME concentration of water and solutes inside and outside the cell, allowing water to move in and out of the cell equally.

Front

What is a solvent?

Back

The liquid substance you add to a solute to make a solution.

Front

What is homeostasis?

Back

A state of relatively constant internal physical and chemical conditions maintained by an organism despite changes in internal and external environments.

Front

What is diffusion?

Back

The movement of all particles except water from an area of high concentration to an area of low concentration across a semipermeable membrane.

Front

What is a solute?

Back

The substance you add to a solvent to make a solution.

Front

What is osmosis?

Back

The movement of water molecules from an area of low solute concentration to an area of high solute concentration across a semipermeable membrane.

Front

What is selective permeability?

Back

The property of a membrane that allows certain molecules to pass through while blocking others.

Front

What is a hypertonic solution?

Back

A solution with a higher concentration of solutes compared to the inside of the cell, causing water to move out of the cell.

Front

What is a hypotonic solution?

Back

A solution with a lower concentration of solutes compared to the inside of the cell, causing water to move into the cell.

Front

What is equilibrium in the context of diffusion?

Back

A state where the concentration of particles is equal throughout a space, resulting in no net movement of particles.
