3.3.3 - Movement of water through plants.
Karten in diesem Stapel (8)
- 1What's the name of a gap in cell walls containing cytoplasm which connects two cells?Plasmodesmata.
- 2Describe the apoplast pathway.When water molecules move freely between the gaps between cells. movement is by mass flow.
- 3Describe the symplast pathway.When water passes through the cytoplasm via plasmodesmata.
- 4Describe the vacuolar pathway.Water is able to pass through the vacuoles as well as cytoplasm.
- 5What is the water potential of pure water?0.
- 6Which direction does water flow?From high water potential to low.
- 7Describe water uptake.Water flows down the concentration gradient, making the cell turgid and exerting a pressure potential.
- 8Describe water loss.Occurs when environmental water potential is much lower, causes plasma membrane to detach from cell wall (plasmolysis) = flaccid.
