Question
please answer table 6b with the plot or graph (number 8 instruction) thank you! Section E. Estimation of the Water Potential (Ψw) of Storage Tissue by Volume Change Method
A similar experiment is as follows:
1.
Obtain 11 (50-ml capacity) beakers and mark
from 1-11.
In each beaker add 20 ml of one concentration of
the following sucrose solutions: Distilled water, 0.1.,
0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0 M
3.
2.
Using a cork borer, cut 55 cylinders from a large
potato or any storage tissue and trim each cylinder to
0.5 cm in length.
Place the cylinders in a covered beaker as you
cut them to prevent them from drying up.
Divide the cylinders in sets of 5. Weigh each set
(to 0.01 g). Put one set of cylinders in each of the
beakers.
4.
5.
Record the fresh weights of each set in
Table 6.
After 90 minutes, remove the cylinders, gently
blot dry with paper towels and reweigh.
7.
6.
Subtract the initial weights from the final weights.
Divide the difference by the initial weight and multiply
by 100 to get the % weight change. Complete Table 6.
8.
Plot the% change in weight (y, ordinate) vs.
sucrose concentration (x, abscissa) on a graph. Draw
the best fit straight line through the points.
