Examples of osmosis in the following topics:
-
- Osmosis is the movement of water across a membrane from an area of low solute concentration to an area of high solute concentration.
- While diffusion transports materials across membranes and within cells, osmosis transports only water across a membrane.
- Osmosis is a special case of diffusion.
- In osmosis, water always moves from an area of higher water concentration to one of lower concentration.
- Describe the process of osmosis and explain how concentration gradient affects osmosis
-
- Osmotic pressure is the pressure needed to nullify the effects of osmosis and is directly influenced by the amount of solute in the system.
- Osmosis is defined as the net flow or movement of solvent molecules through a semipermeable membrane through which solute molecules cannot pass.
- Imagine osmosis taking place in an upright U-tube.
- Osmotic pressure can also be explained as the pressure necessary to nullify osmosis.
- Eventually the added weight of the extra water on the left causes enough pressure to stop osmosis.
-
- Osmosis is the net movement of solvent molecules through a partially permeable membrane into a region of higher solute concentration.
- The intent of osmosis is to equalize the solute concentrations on the two sides.
- Osmosis is essential in biological systems because biological membranes are semi permeable.
- Osmosis provides the primary means by which water is transported into and out of cells.
- If the medium is hypotonic — a diluted solution with a higher water concentration than the cell — the cell will gain water through osmosis .
-
- These include diffusion and osmosis.
- Osmosis is driven by the imbalance in water concentration.
- Both osmosis and dialysis are used by the kidneys to cleanse the blood .
- Osmosis will be to the right, since water is less concentrated there.
-
- Passive transport, such as diffusion and osmosis, moves materials of small molecular weight across membranes.
- The passive forms of transport, diffusion and osmosis, move materials of small molecular weight across membranes.
-
- Water passes through the membrane in a diffusion process called osmosis.
- Osmosis is the diffusion of water through a semi-permeable membrane down its concentration gradient.
- Osmosis is the diffusion of water through a semipermeable membrane down its concentration gradient.
-
- Tonicity, which is directly related to the osmolarity of a solution, affects osmosis by determining the direction of water flow.
- Tonicity describes how an extracellular solution can change the volume of a cell by affecting osmosis.
-
- Osmoregulation is the process by which living things regulate the effects of osmosis in order to protect cellular integrity.
- Various living things have ways of controlling the effects of osmosis—a mechanism called osmoregulation.
- Describe the methods by which organisms regulate the effects of osmosis on their cells
-
- Under these conditions, water flows from the environment into the cell by osmosis.
- In Paramecium, which, presumably, has the most-complex and highly-evolved CV, the vacuole is surrounded by several canals, which absorb water by osmosis from the cytoplasm.
-
- Another important form of fluid movement is osmosis—the transport of water through a semipermeable membrane (shown in ) from a region of high concentration to a region of low concentration.
- Both osmosis and dialysis are used by the kidneys to cleanse the blood, and the medical application of dialysis through machinery is important in the treatment of individuals with failing kidney function.
