like lemonade powder
What is equilibrium?
equally concentrated on both sides of the membrane
where does the cell cycle begin with? (not the stages ex: G1)
it all begins with a fertilized egg
What is the cell cycle?

What type of transport requires extra energy?
active
What is a solvent?
what does the dissolving
What is simple diffusion?
the spreading out of molecules across a membrane until equilibrium is reached

What type of cell transport goes from high to low concentration?
passive transport
what is the solution?
the uniform mixture of two or more substances

What does active transport do?
brings materials into the cell or expels materials out of the cell
What is the concentration?
