what is exact definition of osmosis?
Osmosis is the movement of water across a semipermeable membrane from a higher concentration of water to a lower concentration of water without the use of energy.
Describe the process of osmosis?
Osmosis is a passive process and happens without any expenditure of energy. It involves the movement of molecules from a region of higher concentration to lower concentration until the concentrations become equal on either side of the membrane. Any solvent can undergo the process of osmosis including gases and supercritical liquids.
Difference between osmosis and diffusion?
Diffusion is the movement of substance (anything- solid ,liquid, gas, etc.) from a higher concentration gradient to a lower concentration gradient.Osmosis is the net movement of water molecules from higher concentration gradient to a lower concentration gradient through a partially permeable membraneSo the difference is that diffusion involves movement of any particles/ substance (e.g. solid, liquid, gas) while osmosis can only occur with water.Another one is that diffusion can occur with or without a membrane but osmosis can only occur with a membrane.Hope this helps. :)
What is the different between Diffusion and Osmosis?
Osmosis is the movement of a solvent (water) into a cell where the concentration of a solute is higher, the lower concentration of solute being outside the root cells. Diffusion involves the spreading of a solute from areas of higher concentrations to areas of lower concentration within a solvent.Osmosis is made possible by a semi-permeable membrane which allows the solvent in, instead of allowing the solute out.Diffusion is the movement of molecules or ions from high concentrated medium to low concentrated medium due to the continuous free movement of molecule , that doesn't require any membrane , simply it's like the movement of perfume molecules in room so that you can smell it everywhere in the room , Osmosis is the same as diffusion but first it has to be water second there must be a semi-permeable membrane or a selectively permeable one between mediums ...Pretty much osmosis is the diffusion of water molecules from an area of high to low cand diffusion is the movement of any molecule from an area of high to an area of low cso osmosis is diffusion just the diffusion of water.Diffusion: it is the movement of molecules from a region of high concentration to a region of low concentrationOsmosis: it is the movement of specifically water molecules from a region of high water potential to a region of low water potential through a partially permeable membrane. Osmosis is only ever the movement in LIQUID such as water, from a high concentrated area to a less concentrated (works against the gradient).Diffusion has the same theory, but is usually with gas.* Diffusion can happen within liquid too. It is only water that moves in osmosis.
How does osmosis form?
Osmosis is a physical process in which a solvent moves, without input of energy, across a semipermeable membrane (permeable to the solvent , but not the solute) separating two solutions of different concentrations. Osmosis releases energy, and can be made to do work, as when a growing tree root splits a stone.
Movement through a cell membrane without using energy is?
I've transport.

Can you have diffusion without osmosis?
Osmosis is the movement of water molecules across a semipermeable membrane from a region of higher concentration to a region of lower concentration. Diffusion is the movement of any molecules from a region of higher concentration to a region of lower concentration. so yes it is possible to have diffusion without osmosis.
Can diffusion occur without membrane?
Diffusion is the movement of molecules kineticly from an area of high concentration to an area of low concentration until they are evenly distributed. Osmosis is the movement of molecules thru a membrane.
Why is osmosis special type of diffusion?
Osmosis is considered a specialised type of diffusion because it ONLY involves water passing from a region of high water potential to an area of low water potential through a partially-permeable membrane. Osmosis takes place primarily in our small intestines, where water is absorbed.
What is one way osmosis and diffusion are similar?
The similarity is that they both involve the movement of molecules between a membrane. In osmosis, water diffuses through a semi-permeable membrane without energy due to a difference in solute concentration between sides. In active transport, energy is used by the organism to "push" molecules through ports in the membrane, regardless of solute concentration.
Can osmosis occur in the absence of menbrane?
Osmosis is a type of diffusion that occurs with a semi permeable membrane. It can therefore not occur without a membrane because that is what differentiates it from diffusion.
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!!!
What is net movement of substances across plasma membrane without additional energy?
Diffusion. With the need of energy, it would be called active transport.
How does osmosis take up water?
Osmosis is the transfer of a solvent (e.g. water) through a semipermeable membrane from a less concentrated solution on one side to a more concentrated solution on the other side. Osmosis is driven by ordinary statistical diffusion, the same movement of solvent occurs even without the membrane but the membrane prevents other types of mixing (e.g. mechanical, convection) that would allow mixing of solutes in the solutions. Only mixing by diffusion through the membrane is allowed.
