Simply, it is the opposite of active transport. It does not "spend" chemical energy. Since passive transport is diffusion, molecules will move from higher areas of concentrations to lowers areas of concentrations and no outside force is needed (unlike active transport).

∙ 9y agoBoth osmosis and diffusion are called passive transports. This is because particles are transported from a higher level of concentration to a lower level of concentration region without assistance from any other sources.

∙ 14y agoBecause engergy is not required for this process. The substance moves from the area of higher concentration across the membrane to the area of lower concentration until the concentrations are equal.
Wiki User
∙ 13y agoOsmosis is defined as the diffusion of water through partially permeable membrane. Therefore, we can consider osmosis a special form of diffusion. Since the direction of the flow of fluid is always down the concentration gradient and both of them do not consume any ATP, they are both passive transport.
Except for that, an active transport involve the fluid flow against the concentration gradient and usually consume a lot of ATP. A typical example for active transport should be the sodium-potassium pump.

∙ 15y agoActive transport requires energy in the form of ATP to go opposite the concentration gradient. Passive transport does not require energy because it does not oppose the concentration gradient.

Is oxygen a passive transport or an active transport?
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.
The movement of substances through a cell membrane without the use of cell energy?
Passive transport using osmosis and diffusion. Osmosis only applies to the movement of water down a concentration gradient across a selectively permeable membrane. DOH!!!
Oxygen and carbon dioxide are exchanged in the lungs and through all call membrane an active transport b diffusion c filtration d osmosis?
osmosis
Is facilitated diffusion type of active transport?
Facilitated diffusion is passive transport as no energy is used, and a protein channel is all that's required. After that it is simple diffusion down a concentration gradient. Anything with the word diffusion in it is passive transport. Diffusion is just the principle of passive transport.
What isit called when a molecule moves across a semipermeable membrane into a region of higher concentration?
When a molecule moves to a higher concentration it needs help of a pump. We call this facilitated diffusion. Osmosis only deals with the movement of water.

What are five transport mechanism where by metabolites nutrient or ions cross the cell membrane?
There are many forms of membrane and cell transport. These are the basic transport mechanisms in a prokaryotic animal cell. Facilitated Diffusion Osmosis Diffusion Exocytosis (this takes two forms; phagocytosis and pinocytosis depending on whether the cell is "eating" or "drinking") Endocytosis Carrier Molecules/Channel Proteins

It is called passive diffusion.
What is the passage of water through call membranes?
simple answer osmosis defined as the diffusion of water from a area of high concentration to a area of low concentration.
When wilted salary is soaked in water it becomes crisp again due to what?
Osmosis, which is the diffusion of water through the cell membrane from an area of higher concentration to and area of lower concentration. Hope this helps.

Why water flows into a cell when it is in a hypotonic environment?
Water enters cell by diffusion from higher concentration out side to in side due to diffusion pressure .
How do you call the process of absorption of nutrients from the environment?
osmosis
