The reason it doesn't require energy is because the water is just flowing with the concentration gradient. it doesn't need energy for the same reason there is wind. the air is working to the concentration of the air.

What is the source of energy for osmosis?
kinetic
Does osmosis increase free energy in a system?
If you have a system in which the process of osmosis is spontaneously taken place, the free energy of the system is being reduced. Free energy is the one doing the job.
Do carrier proteins require energy?
By definition, osmosis does not require the transport of particles or energy in the process. Osmosis is the movement of water through a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration.
Does active transport require the cell to expend energy?
Yes, require to spend energy
How do objects acquire potential energy?
For an object to require potential energy a force must be acting on it in a certain direction. Even though the object doesnt move doesnt mean it has potential energy. The most common force of otential energy is Gravity. When an object is lifted off the ground gravity becomes stronger. For a formula of proof then use E=FxD (Energy=Force applied x Distance travelled). If a ball has been lifted by 10 Meters with a force of 500 Newtons then it has a Potential Energy of 5000 Newton Meters,
Osmosis does not require what?
Osmosis does not require a cell to expand its own energy. Osmosis is a type of diffusion process for water.
What process requires membrane proteins but not energy?
Osmosis is the membrane activity that does not require the expenditure of energy by the cell. It does not require any input of energy.
Is osmosis a natural process?
Yes because it does not require energy
Are diffusion and osmosis passive or active transports?
Diffusion and osmosis are passive and do not require energy.
Does osmosis require a carrier?
NO. Osmosis( by definition) is the DIFFUSION of water from a high concentration gradient to a low concentration gradient across a semipermeable membrane. As diffusion is a form of passive transport, it doesnt require a carrier
Does osmosis require a cell to expend its own energy?
No. Osmosis is a passive method of transporting water. It moves water from a high concentration of water to a lower concentration of water. It is really simple diffusion but it is called osmosis because it involves water.
What is the difference between active transport and osmosis?
Osmosis is the diffusion of water across a membrane, and does not require the input of energy. Active transport requires energy input.
Diffusion and Osmosis are passive transport mechanisms meaning they do not require?
They do not require energy, which is often in the form of ATP.
What help maintain homeostasis in cells does not require energy?
Simple diffusion and osmosis help maintain homeostasis in cells and do not require the cell to expend energy.
What does osmosis require that this structure be present?
What does osmosis require that this structure be present?
How is diffusion SIMILAR to osmosis?
Neither of them require energy. that is the major difference.
What process does not require energy to move a substance across a membrane?
Osmosis because it is the equalization of pressure.
