Osmosis

Parent Category: Chemistry
Osmosis is the passing of liquid, through a semipermeable material, from a low solute concentration to a high solute concentration.
Osmosis is a special form of diffusion in that it brings water into  a cell, rather than nutrients & other substances.
a semi-permeable membrane
An analogy for osmosis would be a crowd of people standing in a  small room, there are a lot of people and they are uncomfortable.  Some of the people will move to another room if there is another  room and it is less crowded.
No, osmosis is a special type of diffusion in which a water  molecule is able to passively transport through a membrane without  a protein. Although it is polar, it's extremely small size makes  this possible
Molecules travel across the cell membrane from a higher concentration to a lower concentration during both osmosis and diffusion. Diffusion is when molecules move across the cells' membrane from a higher concentration to a lower concentration. Osmosis is the diffusion of water.
The movement of water across a semipermeable membrane.
It's not a response, it's diffusion. Water diffuses to regions with  higher concentrations of ions, as the dilution of the ions is  thermodynamically favourable.
It's used to maintain the concentration of cell cytoplasm,  extracellular fluid and mucus.
Substances may pass through membranes in cells to exchange gases in  the alveoli in the lungs or liquid in the nephrons in the kidney.  As blood circulates, it encounters such areas and wastes are  deposited into the kidneys or air is taken up by the lungs which is  passed into the blood.
Osmosis occurs when there are two solutions of different  concentration strength separated by a semipermeable membrane. The  membrane must allow water to cross, but not the solutes. Water will  then move from the solution of lower concentration strength across  the membrane to the solution of...
Osmosis is the diffusion of water across the cell membrance
Osmosis is a type of passive transport that occurs when water  diffuses through a cell membrane.
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. ...
No - neither of these require any energy input. They are therefore examples of passive transport. They both involve movement from areas of high concentration to areas of low concentration.
Osmosis across the cell membrane doesn't occur when the concentration gradients, and therefore the water potential inside and outside of the cell are the same
Diffusion:- The molecules of any substance move away  from the region of higher concentration to the region of lower  concentration. Such movement is random and this process is called  diffusion.   Osmosis:- Osmosis is slightly different from  diffusion, because in osmosis, some kind of...
boiled potatoes permeable
if you mean 'invented', no one invented it, it occurs naturally. it was naturally
No. Osmosis is passive, meaning it does not require ATP.
Osmosis is the movement of water across a partially permeable membrane down the concentration gradiant from an area of high concentration to an area of low concentration until an equilibrium is achieved.
Yes. Osmosis is a type of diffusion involving the movement of water through a semipermeable membrane from a solution with a low solute concentration to a solution with a high solute concentration, until the concentration of fluids on both sides of the membrane is equivalent.
Because osmosis is the movement of water molecules from where they are in high concentration to where they are in low concentration.
diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration

Osmosis is the process where Water Molecules move from a solution with a Higher Water Potential to a solution with a Lower Water Potential through a Partially Permeable Membrane.
Osmosis in plant cells. (water moves into plant cells by osmosis). Osmosis in animal cells. (water also diffuses in and out of animal cells by osmosis).Hope this answers your question.
Osmosis is the diffusion of molecules from where they are abundant to where they are scarce through a semi permeable membrane.In red blood cells, this semi permeable membrane is the cell membrane. If red blood cells were placed in a solution abundant with water molecules, they would diffuse into the...
Yes it could! Since animal cells are not protected by a cell wall, they run a risk of bursting. Hence, animals which live in freshwater have a much greater need of mechanisms that enable them to remove excess water. If not, they'll burst!
I think that the osmosis works best at higher temperature. At higher temperature, the water molecules will have more kinetic energy and move faster thus increasing the process of osmosis.
Because it needs no energy apart from that of the molecules.
Yes, osmosis is how water travels between cells.
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 the movement of water through a semi-permeable membrane. When there are different concentrations on either side, the water moves from the side that has the least concentration of solute to the side with the higher concentration of solute. So a different solute concentration drives osmosis...
A selectively permeable membrane
Osmosis is a very specific type of diffusion. Osmosis is defined as  the movement of water from higher concentration to lower  concentration. This type of diffusion is unique as it only really  involves water movement which occurs through a membrane that is  considered semi-permable.
A potato is used in the osmosis experiment.
Water potential gradient is caused by active transport of salts into xylem, this creates a force which makes water move up the plant, this force is known as root pressure
Osmosis is the the diffusion of water or any soluble liquid across a semipermeable membrane such as the outer membrane of a cell.When water moves out of the cell faster then the intake of water, the cell will shrink. This is a hypertonic solution. When the intake is greater than the output, the cell...
Osmosis is the passive movement of water particles from an area of high concentration to an area of low concentration through a concentration gradient.
The movement of water through the root hair cells takes place via osmosis. The concentration of water in the roots is however greater than the concentration of water in the soil and thus the movement of molecules across the concentration gradient will require energy. thus the osmosis in plants is an...
Osmosis is the diffusion of water or another solvent from a more dilute solution (of a solute) to a more concentrated solution (of the solute) through a membrane that is permeable to the solvent.
  Theoretically, the maximum point of increase in the rate of osmosis with the increase of temperature should be the boiling point of water. At this point, the water can not get hotter (without superheating due to the addition of pressure), therefor the rate of osmosis could not be any greater. ...
Its just like diffusion instead, osmosis moves high WATER consentration to a low WATER consentration.
The higher the temperature the faster diffusion occurs which in turn means that the process of osmosis becomes faster as the temperature rises.
The difference between diffusion and osmosis is that diffusion is the passive movement of particles from an area of high concentration to an area of low concentration down the concentration gradient. Particles will continue to move until dynamic equilibrium is reached, which is a state where the...
concentration- hypertonic or hypotonic
  The second law of thermodynamics states (to the effect) 'Entropy is always increasing.' This means that there is energy to be found is spreading out. As osmosis obeys the 2nd law then it is energetically favourable that it should occur.Because water can dissolve into and pass through...

No. Osmosis refers to the movement of water only. Gases move by diffusion.
it takes place in a plant cell
Osmosis is the movement of water from an area of higher concentration to an area of lower concentration through a partially permeable membrane.
both move substance from area of higher conentration to an area of higher conentration
osmosis is the movement of water through a semi-permeable membrane.if you know what facilitated means then add what diffusion means
Osmosis is the movement of water across a selectively soluble membrane driven by a difference in solute concentrations. Osmosis in plants is the absorption of water from soil through the roots.
Water or liquid move naturally from lower concentration to higher concentration. The drive force is called osmotic pressure. No additional pressure need to drive osmosis process.Reverse osmosis, is apply pressure to fight against osmotic pressure. It do need additional pressure to reverse the...
  Osmosis is the movement of water molecules across a selectively permeable membrane.
if the membrane is intact and there is a change of concentration of solut or solvent, osmosis should happen.
Diffusion. Osmosis is the diffusion of water across a membrane.Osmosis is a special type of diffusion. It is the movement of water molecules only from a solution of higher water potential to a solution of lower water potential across a selectively permeable membrane.The characters in bold indicate...
osmosis is to do about plants so it is diffusion hope this helped
osmosis is a natural physical process in which water (i.e. molecules of water) moves across a selectively permeable membrane from an area of high concentration to an area of low concentration so as to maintain equilibrium. it's sort of like diffusion, except only for solutes, or more specifically,...
  == reverse osmosismay be define as a separation operation involve transfer by concentration gradient of a solvent through membrane in to a mixture solute and solvent , the transfer of solvent in the opposite direction is effected by imposing the pressure . is known as reverse osmosis ==
That depends on what it's made from. If it's known to come from a non-kosher source, then it's not kosher. But if the source material is unknown it can be presumed to be kosher.
osmosis is diffusion through a membrane
osmosis in human cells
Diffusion of fluid through a semipermeable membrane from a solution with a low solute concentration to a solution with a higher solute concentration until there is an equal concentration of fluid on both sides of the membrane .
Really? osmosis.
Both involve passive transport: The movement of molecules from a region of higher concentration to a region of lower concentration in order to reach a state of equilibrium.
Diffusion is the movement of molecules from an area of higher concentration to areas of lower concentration. Osmosis IS diffusion, but only refers to diffusion through a membrane,and usually refers to the movement of water.
marine organisms have a low concentration of salt and a high concentration of water, the water tries to leave the cells of the organism because of the concentration gradient (the low concentration of water in the salt water in comparison), so the organism has to overcome osmosis.
The water tank used a reverse osmosis filtration system.Plants use osmosis to obtain water through their roots.Sleeping on a book will not transfer the knowledge by osmosis.
diffusion does the thing and osmosis does the other one. 10/10  gameinformer
water. its just like diffusion but with water. through aquaporins or somthin like that
Osmosis is the movement of water molecules through a membrane.    Diffusion refers to the movement of molecules into and out of a  cell. Osmosis pertains specifically to the movement of water  molecules.
Most membranes are semi-porous and osmosis (movement of water) occurs. In many plants the cells have a waxy coating which limits the movement of water.
Never. It`s a passive transportation.
In a general sense, osmosis flows into a plant. Provided that osmosis is the diffusion of water molecules that pass through a semipermeable membrane to equalize the overall concentration, there are a few conditions where the plant cells will respond to different forms of solutions; as evident by the...
nothing because the membrane is to keep out some things and let other things in nothing to do with osmosis at all
the tendency of a fluid, usually water, to pass through a semipermeable membrane into a solution where the solvent concentration is higher, thus equalizing the concentrations of materials on either side of the membrane.
Agre tested his hypothesis in a simple experiment where he compared cells which contained the protein in question with cells which did not have it. When the cells were placed in a water solution, those that had the protein in their membranes absorbed water by osmosis and swelled up while those that...
Mitosis is the process of cell division. Osmosis is the dispersion of water molecules across a semipermeable membrane, along the gradient of high concentration to low concentration until balance is reached on both sides. Two very different processes.
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. ...
it doesn't. you may have asked the question wrong! however, osmosis is slightly like diffusion, it involves water molecules. Osmosis consists of water moving from a high WATER concentration; to a low WATER concentration. extra information: diffusion, is just the process of a substance moving from a...
Physical. The water is not changed chemically, it is just moved by diffusion across a membrane.
osmosis is in living organism .osmosis is a flow of liquid from higher concentration to lower concentration . all living organisms undergoes this process.for eg: due to over heat our body undergoes osmosis process by emitting the sweat outside
  No, actually diffusion is a kind of passive transport, and osmosis is a kind of diffusion. Any passive transport can happen without energy (contrary to active transport). Since, all the things you listed were passive transport, they happen down the concentration gradient and need no ATP.
water is a basic need of plant's the help of water plants make there food and this process is known as photosynthesis
1. it passages water from high water potential to low water potential through a semi-permeable membrane 2. it helps plant stand up straight in the sunlight
Water moves through the membrane towards the side that has a higher dissolved solute concentration. Another way to look at it is that the water moves in the direction that results in equal concentrations on both sides of the membrane.
