u did bad or was it really easy when u say pathetic?

cmon guys it was da easiest practical.. easier than 33... Mine went gud...

* Now tel me k vat were da order of solutions S1,S2,S3,S4?
* Vat variables had to be controlled in NaCl exp.?
* In plan drawing how many layers u guys draw?
* In xylem only lignin deposition had to be drawn na? Plz reply asap! Thnx..

I think the solutions were in the order S2, S4, S3, S1
You could have written temperature, length of the tissues being used, part of the plant where the tissue came from, and same water potential. Temperature: by use of thermostatically controlled water bath, and water potential: soaking all tissues in the same solution (of same sucrose or NaCl concentration) for at least 24 hours, and replacing with another fresh solution for the next few hours.
I think there were three layers in the plan, one slightly below the vascular bundles.
Yes, you had to draw only two different lignin deposits on the xylem vessels. One was spiral, the other band-like.
