How is osmosis a special kind of diffusion?
Osmosis is a special kind of diffusion because it specifically involves the movement of water molecules across a selectively permeable membrane. In osmosis, water moves from an area of higher concentration to an area of lower concentration to achieve equilibrium. This process is important for maintaining the balance of fluids in cells and tissues.
Is osmosis a form of diffusion?
Yes, osmosis is a specific type of diffusion in which water molecules move across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
Who discovered osmosis and when?
Osmosis was discovered by a French physiologist named Henri Dutrochet during the early 19th century. He first described this phenomenon in 1826 while studying the movement of fluids in plant tissues.
Reverse Osmosis is the method of producing pure water by forcing saline or impure water through a semipermeable membrane across which salts or impurities cannot pass. Reverse osmosis is used for water filtration, for desalinization of seawater, and in kidney dialysis machines.
Is energy required for osmosis?
No - osmosis is a passive process. It is the movement of water into an area of higher solute concentration in order to achieve equilibrium. It can also sometimes be used to describe the movement of another solvent (not water) in a similar manner.
Water is the primary molecule that undergoes osmosis. Osmosis is the movement of water molecules across a semipermeable membrane from an area of higher water concentration to an area of lower water concentration in order to equalize the concentrations on both sides of the membrane.
How does water move through osmosis?
Osmosis is the diffusion of a solvent (usually water molecules) through a semipermeable membrane from an area of low solute concentration to an area of high solute concentration, or conversely from an area of higher water potential to an area of lower water potential.
Water will tend to flow from a hypotonic solution (low concentration of dissolved substances) into a hypertonic solution (higher concentration of dissolved substances).
Water will in essence push or thrust (Greek osmos,push,thrust) from a place of low concentration of water to that of a high concentration of water as it requires it. The membrane allows only water and some select substances to pass through.
What particles move during osmosis?
During osmosis, water molecules move across a semipermeable membrane from an area of high water concentration to an area of low water concentration. Other particles (ions or molecules) may also move with the water if the membrane is permeable to them.
Does hypotonic solution cause osmosis?
Yes, a hypotonic solution can cause osmosis. In a hypotonic solution, there is a lower concentration of solute outside the cell compared to inside. This creates a concentration gradient that causes water to move into the cell through osmosis, potentially leading to cell swelling or bursting.
How do substances move in diffusion and osmosis?
Diffusion- This is the movement of substances from an area of high concentration to low concentration. Diffusion can be sped up by heat and by increasing the concentration of the diffusing substances. Osmosis-This is the movement of water down a concentration gradient across a semi-permeable membrane. Water crosses the membrane down its concentration gradient, from the side with the lower solute solution to the side with the higher solute solution. This is therefore making the lower solute solution more concentrated, while also diluting the higher solute concentration solution. Osmosis will carry on until equilibriium is reached which is said to be isotonic, when both sides have reached their equal concentrations. Emms B x
How does the concentration gradient affect osmosis?
The concentration gradient in osmosis refers to the difference in solute concentration between two solutions separated by a semi-permeable membrane. Water will move from an area of low solute concentration to an area of high solute concentration in an attempt to equalize the concentration on both sides of the membrane. The steeper the concentration gradient, the faster the rate of osmosis.
It is not incorrect. There is a sentence to remember: "water follows salt". This always true concerning a semipermeable membrane. Water can go either way and has no need for any sort of transport mechanisms. It will try to make the "salty" side more like the "less salty" side to even them out.
Osmosis is the passive movement of water molecules across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration. Active transport, on the other hand, requires energy to move molecules against their concentration gradient, typically with the help of carrier proteins. Both processes play crucial roles in maintaining cell homeostasis and ensuring proper nutrient uptake and waste removal.
How would you use osmosis in a sentence?
Osmosis is the diffusion of water molecules from an area of high concentration to an area of low concentration, usually through a semi-permeable membrane.
How does osmosis explain sugar on strawberries?
Osmosis explains the process by which sugar molecules move from an area of high concentration (syrup) to an area of low concentration (strawberries). When strawberries are placed in sugar syrup, water inside the strawberries moves out through osmosis to balance the concentration, causing the strawberries to absorb the sugar and become sweeter.
What effect does a temperature increase have on osmosis?
I'm not sure about it, but this is my answer:
As temperature increases, each process in the universe speeds up. So does osmosis. But: temperature also changes equilibrium. And, it often does so in an unpredictable way. So, you can't say if more water goes out of a cell (or whatever your system is), or on the other hand less water goes out.
(WATER CELLS ONLY)
Water cells move from a higher concentration gradient (more water cells) to a lower concentration gradient (less water cells) through a partially permeable membrane (allows certain substances in and out) and goes with the concentration gradient (high -> low)
What kind of transport is osmosis?
Osmosis is the diffusion of water through a semi-permeable membrane (from a low-concentration gradient to a high-concentration gradient).
Ummm how in the world does that answer the question "What kind of transport is Osmosis?" Is it Active or Passive that's what we want to know however I do believe from my information that the answer in which we are looking for is PASSIVE. PLEASE correct me if I am incorrect and excuse my mistake.
What is the purpose of osmosis?
There is no overall purpose of osmosis it is used/occurs in many different processes in many living things. Osmosis is genrally reffered to as the net movement of water across a membrane. This genrally happens due to a water potential imbalance but can also occur due to active transport.

In plants, osmosis keeps the plant cells turgid, this means that the cells have swelled up from the additional water and become hard. As plant cells have a strong cell wall around the cell they do not burst from containing too much water. Plant cells are normally turgid, especially in the day, to keep their leaves upright to photosynthesize and catch as much sunlight as possible. Water also enters into the plant through osmosis in the roots.

Transfer of water molecules across a membrane to attain balance between inside and outside. This is just the general nature of things, a law of physics/micro-biology I guess.
it is movement of molcuse from high concentration to low concentration
eg
- Plants
Animals

Osmosis is a form of transport. In some cases It is transport of water into cells.
Osmosis is the movement of water molecules from a region of higher concentration to a region of lower concentration through a selectively permeable membrane. This process helps to balance the concentration of solutes on either side of the membrane.
The aim of osmosis is to equalize the concentration of solute on both sides of a selectively permeable membrane. Water moves from an area of low solute concentration to an area of high solute concentration to achieve this equilibrium.
Difference in osmosis and diffusion?
Diffusion is the spread of particles through random motion from regions of higher concentration to regions of lower concentration....
Osmosis is the net movement of solvent molecules through a partially permiable membrane into a region of higher solute concentration, in order to equalize the solute concentrations on the two sides....
During osmosis, water molecules move across a semi-permeable membrane from an area of higher water concentration to an area of lower water concentration, in order to equalize the concentration of solutes on both sides of the membrane. This movement of water helps to maintain the balance of fluids and solutes in living organisms.
How does osmosis and diffusion differ?
Osmosis is a type of diffusion but through a barrier (membrane) while "diffusion" is not specified if there is a physical barrier or not. Gases diffuse through each other readily.
Osmosis requires a semipermeable membrane, such as a cell membrane, that allows water molecules to pass through while blocking the passage of solute molecules. It also requires a concentration gradient, with higher concentrations of solute on one side of the membrane compared to the other, to drive the movement of water molecules.
