Oh thank you so much...! Jazaki Allah khairan.. May Allah reward you for your help. May you get the highest grade in this life and hereafter. Good luck.Hi PhyZac
Well, cell 3 is a xylem vessel, whilst cell 2 is a "normal photosynthesising cell" and cell 1 a phloem cell. so you would expect that the water potential in cell 3 to be much less negative than the other cells because it contains water mainly. cell 2 will be less negative than cell 1 as cell 1 has a high conc. of sugars so has a less water potential. so the answer there must be A only.
for the second question according to me is the goblet cell because it releases a great deal of mucus, so it is bound to contain smooth endoplasmic reticulum (structure responsible for release of proteins.
Hope my answer helped u and good luck.

Hi Hassan.CAn someone help me with ho0w to find the uncertaininty after finding the length of specimen??

Hi Hassan.
Well, uncertainty is found using the smallest division of the instrument u used to measure divided by 2. For instance if u used a ruler, the smallest div. is 1 millimetre, so the uncertainty will be +- 0.5 mm
P.S I haven't had a look at the question, i just told u the way of doing it, now apply the same logic specifically to the question.
Hope my answer helped u.
