It is passive transport because of the diffusion.
passive transportPassive transport is the term. Active transport is moving of materials WITH energy.Passive transportpassive transportdiffusionDiffusion, but if it's water then it's called osmosis. They're the same basic thing though.diffusion
They transport fluid/water/materials across the cell memebtane
Carbon dioxide cannot be transported across the membrane by passive transport. However, water and sodium ions can be transported using passive transport.
active transport -transport against concentration gradient that requires chemical energy passive transport- requires no energy at all
passive transport does not require energy eg. diffusion and osmosis. Therefore, osmosis is a passive transport. Active transport requires energy eg. a molecule going from a low concentration from a high concentration.
The name of the membrane that allows movement of water and substances through the process of active and passive transport is semipermeable membrane.
It is passive transport because of the diffusion.
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.
Diffusion is an example of passive transport, like osmosis(the diffusion of water through a membrane).
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.

It is a type of passive diffusion, as the water travels along a concentration gradiant. As opposed to active transport, where the substances can pass against a concentration gradiant.
Diffusion. It's the movement of water through a permeable membrane. And it's always passive.
Proteins that carry out passive transport include channel proteins and carrier proteins. Passive transport is "passive" because it does not use energy. The use of passive transport is also called "facilitated diffusion." Proteins that carry out passive transport includes the proton pump and the sodium-potassium pump; these require energy to function.
It is passive transport because the water flows from a more highly concentrated solution to a less concentrated solution.
Active transport requires energy, whereas passive transport does not. Passive transport is normally something moving from an area of high concentration to low concentration (with the grain). Active transport is something moving from an area of low concentration to an area of high concentration(against the grain).
