Particles move from where they are in high concentration to where they are in low concentration.
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 concentration gradient and the membrane
The processes that can move a solute against its concentration gradient are active transport. All cells are enclosed by a plasma membrane that is similar in structure and function.
Yes. Transport that goes down a concentration gradient is spontaneous and therefore does not require energy.
yes, Movement of substance down its concentration gradient is a passive transport because it going from high concentration to a low concentration, so it does not require any energy.
Passive transport moves molecules from a high to low concentration gradient.
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 concentration gradient and the membrane
The concentration gradient is the driving force.
Osmosis is a passive transport process. Therefore it can only go with the concentration gradient.

concentration gradient.
passive transport
Active transport requires an input of energy and can move substabces against their concentration gradient. Passive transport does not require added energy and can move substances only down their concentration gradient.
