Chapter 30.3, Problem 1TYK
Summary Introduction
Introduction:
The water pressure inside the plant cells is an important aspect to support the plant and this is done through the process of transpiration. The pressure inside the cell is called turgor pressure that pushes it against the cell wall and is maintained by the process of osmosis. Osmosis is the motion of water molecules through a semipermeable membrane from a lesser concentration of solute to a higher concentration of solute. This is to maintain equilibrium.

- 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?

- In plants, water is transported through vessels called xylern. The cohesiveness of water molecules allows them to travel up the walls of the vessel. However, for most plants this is not enough to move the water all the way to the top of the plant. How do plants overcome the force of gravity and move water to their upper tissues ? Root hairs push water through the roots and up into the xylem. Plants absorb water through transpiration to supply their upper tissues with water . С The guard cells surrounding the stomata expand and contract, pushing water through the xylem. Water escapes from the leaves through transpiration, creating a vacuum which pulls water up the xylem.arrow_forwardExplain what would happen if a plant cell was placed in a hypotonic environment and why (be sure to include solute concentrations, water movement and turgor pressure in your explanation)?arrow_forwardin plants , water is transported through vessels called xylem gravity and move water to their upper tissues ?
