passive transport and active transport.
active
Active transport requires energy to move molecules across a membrane against their concentration gradient. This process is facilitated by specific carrier proteins embedded in the membrane that use energy, usually in the form of ATP, to transport molecules.
Carrier proteins are sometimes used during passive transport.
Passive ways of crossing the plasma membrane include diffusion and facilitated diffusion, where substances move across the membrane down their concentration gradient without the use of energy. Active transport, on the other hand, requires energy, typically in the form of ATP, to move substances against their concentration gradient. Examples of active transport include the sodium-potassium pump and endocytosis. Overall, passive transport relies on natural concentration differences, while active transport requires energy input.

active
it moves by diffusion, osmosis and active transport
Molecules can cross the cell membrane through simple diffusion, facilitated diffusion via transporter proteins, and active transport using energy to move molecules against their concentration gradient.
diffusion, osmosis, active transport
Active transport and facilitated diffusion are similar in that they both involve the movement of molecules across a cell membrane, but they differ in that active transport requires energy input from the cell, while facilitated diffusion does not.
there are two ways to transport things into a cell: active and passive transport. In active transport the cell has to physical engulf whatever it needs from outside the cell. In passive transport, if something inside the cell has less of the item that is outside of the cell, the things outside of the cell go into the cell until the number is balanced. This happens automatically so it doesn't involve energy.
That's right... If it doesn't require energy it is passive. Take note of the key word 'active' which tells you it requires energy. But you should have a basic understanding of the main ways molecules cross the plasma mebrane
