The membrane has to be semi-permeable in order for anything to have the ability to pass through it. Usually, something such as water will travel through the membrane from a higher to a lower concentration gradient. This causes the two sides to reach equilibrium. Osmosis can only occur when both sides do not have the same concentration and the membrane has to be at least semi-permeable for fluids to pass through.
What else can I help you with?
What does it take to make osmosis to go backwards?
It requires energy. With a pressure difference, you can revert osmosis.
Does soaking potatoes make them crispy osmosis?
Yes
Why is osmosis crucial for completion of cellular processes?
To make new cells
Does osmosis need sugar?
Yes. Osmosis needs water to finish the final product and to make both sides even. However, they use water as well and bacteria forms to produce a toxic waste. It is impossible to see osmosis but if you use a microscope you can.
Passive transport of water is known as?
floating
Why do diffusion and osmosis happen?
they make the concentration of the solute equal inside and outside of the molecule.
How can OSMOSIS be used to make pure water from saltwater?
By reversing osmosis and using pressure to push the pure water through the semipermeable membrane, leaving concentrated salt brine behind.
What process is the diffusion of water through a selectively permeable membrane?
The process of water passing through a selectively permeable membrane is called osmosis. Water will move from an area of higher concentration to an area of lower concentration in order to equalize the solute concentrations on both sides of the membrane.
Placing limp celery in water will make the celery stalk firm again due to?
osmosis
Can salt be taken out of saltwater by freezing it?
No but you can make Saltwater edible using the Reverse Osmosis Method.
Do cells have to work to make osmosis happen?
No, osmosis is a type of diffusion. Diffusion never requires work. Osmosis occurs when water seeks equilibrium. The water will naturally try to have the same amount of solvents in it without work from the cell. You can do osmosis experiments using a dialysis bag. Put solvent (such as sugar) in the bag with some water. Then put the bag in a cup of water. Watch what happens :)
When raisins absorb water is it diffusion or osmosis?
osmosis
