give an experiment to demonstrate that xylem is the path of ascent of SAP in plants
Answers
Answer:
Explanation:
→ The below mentioned experiment and theories demonstrate the ascent of SAP in plants.
→ The process by which water and minerals translocate from base to apex of the plant is known as ascent of sap. It takes place through complex tissue xylem.
Experiment to Show that Xylem is the Path of Water Conduction:
→ That most of the water is trans-located in the xylem can easily be demonstrated by a simple experiment. In this experiment two small shoots of a woody plant are taken. Their cut ends are so prepared that in one shoot phloem is blocked with wax, while in the other xylem is blocked. Now the cut ends are submerged in water (see fig. 3.1). After some time the shoot with its xylem blocked shows wilting, but the shoot with its phloem blocked remains unaffected.
● Xylem :- It is an pathway in plants which transport Water and Minerals which are absorbed from the SOIL by ROOTS hair .
for this experiment showing we can took a plant in an port and fix a tight strength by any think .
and after some days we can observe plant died beacuse of not transferring raw material .
