When two chambers are separated by a membrane permeable to water but not solute, if water is free to move in either direction without limitation or pressure, then water will
- move until the concentration of solute on both sides of the chamber is equal
- move until there is no water on the dilute side
- move until there is no water on the concentrated side
- move until the concentration of water on both sides of the chamber is equal
Introduction
A solution is a homogeneous mixture of two or more substances. It may exist in any phase such as solid, liquid or gaseous. A solution consists of a solute and solvent. The solute is the substance that is in small quantities that is dissolved in the large quantities of solvent. The amount of solute that can be dissolved in solvent is called its solubility. For solutions with components in the same phase, the substances present in lower concentration are solutes, while the substance present in highest abundance is the solvent. A solvent is a substance that is present in higher quantity.
Transport of solute across any biological membrane is very essential for all life forms. Such a transport is highly regulated in eukaryotes and involves transport proteins to serve the purpose.

- Submerging of a red blood cell in a hypertonic solution will result in Lysis of the cell membrane Bursting of the cell Plasmolysis of the cell The cell becoming turgid The cell becoming flaccidarrow_forwardYour friend has made an artificial membrane to study ion concentration gradients in a laboratory and is confused after observing the ion concentration gradient in the image below. Initially (Time 1) there was a very strong concentration gradient across the membrane and your friend expected that ions would move until the concentrations were equal across the membrane. For a short time there was movement of ions but this soon stopped and there is no further change in the situation no matter how long you wait (see Time 2). Time 1 You friend is confused because there is still a strong concentration gradient and there are open ion channels available. So why don't the concentrations equalise? After thinking about it you realise that there must be some information that is incorrect or missing from the diagram above. Select the image below that explains why the ion concentrations remain unequal across the membrane Time 2 Select the correct image by clicking on it (you can only select one…arrow_forwardHYPERTONIC SOLUTION Water Solute 98% Water Solute Cell Condition:arrow_forward
- When a bacterial cell is placed in a hypotonic, environment, the cell wall restrains the pressure resulting from the greater osmolarity of the cytoplasm. (Use one word in the blank space. Spelling must be correct to earn the point. The word "osmotic" is NOT an answer that that will earn credit for this question; there is another word that is required.)arrow_forwardIf a dialysis tube that is permeable to water but not sucrose contains a 40% sucrose solution that is in a beaker of water, the solution in the beaker is said to be: cannot be determined isotonic hypertonic hypotonicarrow_forwardYou have dialysis tubing that is permeable to water but not sucrose that contain 10 mL of varying concentrations of sucrose solutions that are placed in a beaker with 100 mL of water. In which beaker/bag combination will osmosis happen the fastest? 10% sucrose solution in the dialysis tubing 20% sucrose solution in the dialysis tubing 30% sucrose solution in the dialysis tubing 40% sucrose solution in the dialysis tubingarrow_forward
- Which of the passive transport processes requires hydrostatic pressure to transport molecules across membranes in the body? Multiple Choice Osmosis Filtration Facilitated diffusion Pinocytosis Diffusionarrow_forwardWhich of the following statements is CORRECT in describing the nature of water channels? Group of answer choices It is a channel for the transport of any liquid medium. It is a non-gated channel. It is a channel that can facilitate the transport of sodium ions. It is a channel for active transport.arrow_forwardWhich of the following best describes a hypotonic solution? a-There is a higher concentration of solute outside the cell than inside the cell b-There is a lower concentration of solute outside the cell than inside the cell c-The solute concentration both inside and outside the cell is equal d-Through osmosis, water will enter the cell causing it to swellarrow_forward
- A cell with intracellular osmolarity of 280 mOsm/L is placed into three different containers varying in osmolarity. Which solution from the list would cause the cell to lose water and shrink? 280 mOsm/L 240 mOsm/L 340 mOsm/L NONE of the abovearrow_forwardThe water will move from right to left by osmosis O The water will move from left to right by osmosis V The sodium ions will move from right to left by diffusion The sodium ions will move from left to right by diffusionarrow_forwardMark the flow of water with an arrow for cells that have been placed in solutions of differing tonicity. Indicate what will happen to a plant and animal cell under each of these conditions.
