They move via passive transport. They move by diffusion. It's only active transport if A) the cell is too big or not fatty enough to move through the membrane and needs help or B) is making the molecules move unnaturally (low to high). Osmosis is also passive transport, but only is used when referring to the movement of water.

Passive transport and active transport are transport of materials across membranes. Passive requires no energy, while active does.
Passive Transport, i think.
Active transport requires ATP and passive transport does not. Active transport goes against the concentration gradient and passive transport goes with the concentration gradient and includes osmosis, diffusion and facilitated diffusion.
The two types of cell trnsport it Passive Transport and Active Transport. Active Transport does require energy to move into and out of the cell. Passive Transport doesn't require energy to move into and out of the cell. Hope I helped!
Passive (diffusion).
Passive transport and active transport are transport of materials across membranes. Passive requires no energy, while active does.
Active transport requires energy; passive transport does not.
Active transport requires energy; passive transport does not.
Active transport requires energy while passive transport does not.
