transport in plants

2. what stops cohesion tension meaning transpiration stops
6. what theory states that water is adhesive to other polar molecules and itself so pulls itself along when moving to the cells after the water vapour has moved out of the leaf (WP conc gradient)- it also pulls the xylem cells but the lignin stops it from closing, gravity also pulls the water down creating tension
7. the movement of water through the cell walls, cohesion tension theory, transpiration pulls it through, capillary action- sucks water against gravity through tiny tubes (dead pathway)
8. what kind of energy heats the water around the plant cells (moved from the xylem) meaning it becomes water vapour and moves out of the plant due to a lower WP outside of the plant
13. what kind of cell takes over the unspecialised functions of the phloem- active transport moving sucrose and water to the phloem, explain
16. an increase of this can affect transpiration as well as an increase in wind a decrease in humidity enzymes and glucose
18. what requires active transport to cross the roots membrane

1. what kind of tracers provide evidence for transpiration explain
3. the movement of water through the cells via plasmodesmata, relies on the cytoplasm, living pathway, relies on osmosis
4. the movement of sucrose and water through the phloem
5. the movement of water through the xylem
9. the movement of water from the soil trough the roots
10. what about trees provides evidence about water travelling through the xylem explain
11. what can be done with root pressure and cohesion tension theory(list them)
12. what travels from source (near leaves)to sink (where its needed)
14. a tube made of dead cells reinforced with lignin(stretchy and flexible
15. what process is water moved through the root hair by
17. what kind of experiment provides evidence for transpiration explain
