How come c) is the answer? Wouldn't the fresh water be a hypertonic solution because it would allow water to osmose out of the celery stalk and would make it 'harder' as there is less water

at approximately what concentration is potato cytoplasm and the sucrose solution isotonic? Explain

In conditions of dehydration, plant cells can increase their water retention by regulating the function of some or all of their aquaporins, membrane-bound protein channels that allow water to move through the cell membrane via facilitated diffusion. Which of the following describes a likely mechanism by which aquaporins can be used to regulate the movement of water across the plant cell membrane? A B с D Synthesis of additional aquaporins by the plant cell ribosomes will allow the cell to coun- teract the movement of water out of the cell. Inhibition of ATP hydrolysis will make the aquaporins unable to remove water from the cell and cause more water to remain in the cell. Inactivation of aquaporins will make water molecules unable to move across the plant cell membrane and allow more water to remain in the cell. Inhibition of the plant cell Golgi apparatus will decrease the production rate of vesicles and slow down the exocytosis of water molecules.

A plant cell with a ΨS of -0.65 MPa maintains a constantvolume when bathed in a solution that has a ΨS of -0.30 MPaand is in an open container. The cell has a(A) ΨP of +0.65 MPa.(B) Ψ of -0.65 MPa.(C) ΨP of +0.35 MPa.(D) ΨP of 0 MPa

What would happen to the observed and specific rotation values if you were to halve the path length of the cell used while keeping the concentration the same?

A plant cell placed into a hypertonic solution will experience which of the following effects? plasmolysis expulsion of the excess water using its contractile vacuoles hemolysis entrance of excess water through its contractile vacuoles turgidity

Mark 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. Direction of osmosis Plant cell Animal cell shape shape minor swelling The solute concentration outside the cell is isotonic (or equal) to the inside of the cell. No change swelling and lysis plasmolysis crenation Reset Zoom (a) Outside isotonic The solute concentration outside the cell is hypertonic to the inside of the cell.

An animal cell has an internal concentration of 0.1M of NaCl. You place this cell into a solution with 5M NaCl. Select the true statement below. The solution is hypotonic to the cell therefore the cell will lyse The solution is hypotonic to the cell therefore the cell will shrivel The solution is hypertonic to the cell therefore water will lyse The solution is hypertonic to the cell therefore water will shrivel

A wilted flower placed in a vase of fresh hwater for several hours became stiff and stood erect. When it was placed in a salt solution, it wilted. From this information, which of the following statements BEST describes the cells of the flower?   Group of answer choices hypotonic to both freshwater and the salt solution hypertonic to freshwater but hypotonic to the salt solution hypertonic to both the freshwater and the salt solution hypotonic to freshwater but hypertonic to the salt solution

A) If the potato cells were hypotonic to the surrounding solution, the surrounding solution itself would be what to the potato cells (hypertonic, hypotonic, or isotonic)? B) Were the potato cells submerged in water with no salt hypertonic, hypotonic, or isotonic to the surrounding environment? C) Were the potato cells submerged in 5 g/100mL salt solution hypertonic, hypotonic, or isotonic to the surrounding environment? D) Look at your graph. At approximately what concentration of salt solution would the potato cells have likely been isotonic with the surrounding solution? [Tip: Estimate approximately at what concentration there would have been no change in the average length of potato strips.] dnote -tnote tes On Search Researcher Research (-)…
