Good day everyone ☺️
This is the task list ....please copy your name under what you want to do.
Please not that the deadline for the information is Wednesday,13 September 2023, at 9am
*Abstract*
-
Water potential is the potential energy of water per unit volume relative to pure water in reference conditions. Determination of water potential of potato tissues using gravimetric method highlights the purpose, methodology, and results of the study. In this experiment, the water potential of potato tissues was measured using the gravimetric method, which involves weighing the samples at different water potential levels. The experiment helps us understand the osmotic properties of plant cells. The gravimetric method involves measuring the change in weight of potato tissues when placed in concentrations of sucrose solutions.
*Aim*
- Using the gravimetric technique, the aim is to determine the water potential of potato tissues .
*Hypothesis*
-as the concentration of sucrose solution increases the water potential of the potato tissue will decrease
*Variable*
-Independent: Sucrose concentration
Dependent: final mass of the potato tissue
Controlled variables: length of the potato, circumference of the potato tissue, length of time the potato tissue was left in the solution which was 1 hour
*Materials*
-Potato tissues
-Razor
-Ruler
-10mL measuring cylinder
-Timer
-Thermometer
-cork borer
-0-0.6 M sucrose solutions
-Balance
*Method*

*Method*
-Prepare at least 14 identical tissue samples from the potato using a cork borer. With a razor blade, trim them to the same length (4.0 cm). Make sure that none of the skin's fragments are included.
2. Quickly weigh each cylinder after blotting them on paper towels to remove any extra moisture. Table 1 should contain the weights. Immediately after weighing, move two cylinders to each tube and make sure they are thoroughly submerged in the solution (20 mL of sucrose (0–0.6 molal) into each of the seven tubes with the corresponding labels).
3.Remove the cylinders after an hour, dab off any remaining moisture with paper towels, and weigh them again as in step three. Table 1 should contain the weights. As you weigh the cores, inspect them. (Stiff/limp) Describe their relative turgor.
