In passive transport, particles move across a membrane from an area of higher concentration to an area of lower concentration without the input of energy. This movement is driven by the concentration gradient and does not require the use of transport proteins. Examples include diffusion and osmosis.
It is called passive diffusion.
No, primary transport involves the active movement of ions or molecules across a membrane against their concentration gradient, using energy typically derived from ATP. In contrast, the passive movement of large particles across the membrane is known as facilitated diffusion, which does not require energy and occurs through specific transport proteins. Thus, primary transport is an active process, while passive movement relies on concentration gradients.
The movement of particles across a cell membrane without the use of energy is called passive transport. This process relies on the natural concentration gradient, allowing substances to move from an area of higher concentration to an area of lower concentration. Common types of passive transport include diffusion, osmosis, and facilitated diffusion.
passive transport (e2020 answer)
Passive transport is a process in cells where substances move across the cell membrane without requiring energy input. An example of passive transport is the movement of oxygen and carbon dioxide across the cell membrane through simple diffusion.

The movement of particles from an area of low concentration to high concentration is an active process.
Osmosis is an example of movement of particles from an area without the need of additional energy. If a state is not in equilibrium particles can move from one area to another without additional energy.
Since you are talking about the movement of particles, it would not be osmosis, because osmosis is the movement of water. Technically speaking, you could consider water a particle, but it is assumed that this question refers to movement of soluteparticles, and not solvent particles. Then, to determine if the movement is active or passive, one needs to know if energy is required and if the movement is up or down the concentration gradient. No energy requirement, it is passive. If a source of energy is needed, then it is active transport. Not sure what a protein doorway is. If you mean a pore, then the movement may be passive, or even facilitated diffusion.
It is called passive diffusion.
It is called passive diffusion.
Diffusion and osmosis are forms of passive transport, which is the movement of particles across a membrane without requiring energy input from the cell.
No, primary transport involves the active movement of ions or molecules across a membrane against their concentration gradient, using energy typically derived from ATP. In contrast, the passive movement of large particles across the membrane is known as facilitated diffusion, which does not require energy and occurs through specific transport proteins. Thus, primary transport is an active process, while passive movement relies on concentration gradients.
In biology, diffusion is the passive movement of molecules or particles along a concentration gradient, or from regions of higher to regions of lower concentration. Diffusion is the free movement of particles in a liquid or gas down a concentration gradient.
