I think the following are reasons which would have affected the results obtained by me. The stolons are easily recognized when potato plants are grown from seeds. Water potential is a measure of the kinetic energy of water molecules.
If the solution surrounding a cell has the same solute concentration as the cell then water ill pass equally between them.
Hemerocallis fulva plus a number of Daylily hybrids have large root-tubers, H. Sucrose is soluble in water because it is a disaccharide sugar. Plants have strong cell wall made up of cellulose.
MM, as shown in below table. Some odd results are seen when I am comparing my results with compared to average value. It is thus different in origin but similar in function and appearance to a stem tuber. Biological membrane are freely permeable to water. Root tubers are perennating organsthickened roots that store nutrients over periods when the plant cannot actively grow, thus permitting survival from one year to the next.
I have decided to take 2 sets of results from my classmates, as one set of result may not be accurate because of human error.
Any breakage should be reported to teachers straight away as we are handling with glass equipment which are dangerous to handle if broken.
It as a very high tensile strength which makes the cell to withstand the large pressures that develop within it as a result of osmosis. The inside of a tuber has the typical cell structures of any stem, including a pith, vascular zones, and a cortex.
Because of the use of Borer to cut potato, I will have cylinders with same width and dimensions but the length will differ.Water potential of potato tuber cells - the weighing method The Investigation of Osmosis The investigation was to find the differences in water molecules moving from an area of high concentration to an area of low concentration using potato tubes and varying the concentration of the solutions.
Osmosis In Potato Tuber Cell The Weighting Method Biology Essay. Aim: To determine solute potential of a plant tissue at 20 ºC.
Research question. Determining the Water Potential of Potato Tubers using Gravimetric and Chardakov Techniques 1. INTRODUCTION: Water potential (W) is the measure of free-energy status of water in plant cell, which is the driving force governing the movement of water into and out of the plat cell and affect various metabolic activities (O’Leary, ).
Essay on Investigate the Water Potential of Potato Cells Words | 10 Pages. Investigate the Water Potential of Potato Cells Introduction In my investigation, I hope to determine the water potential of potato cells.
The plant material I will use in my investigation will be potato chips, which I will cut myself prior to the investigation. The solute potential of the potato tuber cells is the same as the solute potential of a sucrose solution in which the potato cylinder did not change in mass.
The concentration of this sucrose solution (where ψsolution = ψcell) mass of the potato cylinder will occur can be determined using the trendline in figure 1. Water potential of potato tuber cells - the weighing method The Investigation of Osmosis The investigation was to find the differences in water molecules moving from an area of high concentration to an area of low concentration using potato tubes and varying the concentration of the solutions.Download
