To determine: Whether water will flow by osmosis from one plant cell with water potential of -1.5MPa to another plant cell with water potential of -1.8MPa.
Introduction: Water is the most crucial factor for a plant to perform its normal cellular functions. The water is absorbed by the roots. The movement of water from the roots to the leaves can be explained using cohesion tension theory of water transport. The water movement from the roots to the vascular tube (xylem) is facilitated by osmosis. Water potential plays an important role in understanding plant physiology because it helps to measure a cell’s ability to absorb water by osmosis.

- What would enhance water uptake by a plant cell?(A) decreasing the Ψ of the surrounding solution(B) positive pressure on the surrounding solution(C) the loss of solutes from the cell(D) increasing the Ψ of the cytoplasmarrow_forwardDuring an experiment, a student covers all the stomata of a plant with nail polish, sealing them shut a)Predict how this would affect water transport b)How would this affect transport in the phloem?arrow_forwardSCIENTIFIC INQUIRY • INTERPRET THE DATA A Minnesotagardener notes that the plants immediately bordering a walkwayare stunted compared with those farther away. Suspectingthat the soil near the walkway may be contaminated from saltadded to the walkway in winter, the gardener tests the soil. Thecomposition of the soil near the walkway is identical to thatfarther away except that it contains an additional 50 mM NaCl.Assuming that the NaCl is completely ionized, calculate howmuch it will lower the solute potential of the soil at 20°C usingthe solute potential equation:ΨS = -iCRTwhere i is the ionization constant (2 for NaCl), C is themolar concentration (in mol/L), R is the pressure constant[R = 0.00831 (L · MPa)/(mol · K)], and T is the temperature inKelvin (273 + °C).How would this change in the solute potential of the soilaffect the water potential of the soil? In what way would thechange in the water potential of the soil affect the movementof water in or out of the roots?arrow_forward
- Describe the pathway water would follow from the soil to the stem of a plant. Describe the water's movement through the cells, tissues, and systems of the plant body.arrow_forwardExplain how being in space would affects the plant growth by analysing the differences and similarity of the functionality of the plant in space and on earth. You have to use the knowledge of transport system as a foundation for your answers. Please answer in detail explanationarrow_forwardImagine yourself as a water molecule in the soil solution of aforest. In a short essay (100–150 words), explain what pathwaysand what forces would be necessary to carry you to the leaves ofthese trees.arrow_forward
- Imagine a cell with a water potential of –0.1 MPa being placed in a beaker of solution that also has a water potential of –0.1 MPa. Are the two water potentials in equilibrium? Would any water molecules be moving between the cell and the solution? Would there be a net movement of water? Now imagine a root in moist soil, and imagine that the root cortex cells have a water potential of –0.1 MPa and that the soil solution also has a water potential of –0.1 MPa. Would there be any net movement of water into the root?arrow_forwardDescribe the pathway water would take up the stem to the leaf of a plant. Describe the water's movement through any cells, tissues, and/or systems of the plant body.arrow_forwardDraw one elodea cell (freshwater plant) after being in saltwater. Label its choloroplast, cell wall, plasma membrane, nucleus, and central vacuole. Which ones are present? 1b) Based on this drawing, which structure is keeping the elodea from going through osmotic lysis in its habitat?arrow_forward
- Explain how osmosis is involved in moving organic nutrients in the plant.arrow_forwardBriefly explain how water moves through a plant. Include how and why water moves through both xylem and phloem.arrow_forwardDescribe the journey of a carbon atom. Begin with it as atmospheric CO2 and end with it as part of a cell wall molecule in a root. Describe a) the structures through which the C atom moves, b) the reason it moves, and c) any cellular process with which it is involvedarrow_forward
