Osmosis and Diffusion Vocab Flashcard

Front

Holes in a cell or nuclear membrane that allow some substances to pass in and out but not others.

Back

Selective Permeability

Front

Liquid added to a solute to create a solution.

Back

solvent

Front

Diffusion of water and substances across the cell membrane from high to low concentration without energy.

Back

passive transport

Front

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

Back

isotonic solution

Front

Amount of solute particles in a solvent; indicates solution strength.

Back

concentration

Front

Diffusion of water from high to low concentration across a semipermeable membrane.

Back

osmosis

Front

A solution with higher solute concentration outside the cell causes water to flow out, leading to cell shrinkage.

Back

hypertonic solution

Front

Passive transport of ions and small molecules across the cell membrane using transport proteins.

Back

Facilitated diffusion.

Front

Substance added to a solvent to create a solution.
