I predict that the swede will have the highest concentration of sucrose and therefore the lower water potential of the two vegetables the reason for this is that swede is a sweet root vegetable where as potato is not sucrose is a sugar present in root vegetables and has a sweet taste, so i think that the swede will contain the. Solutions of various concentrations 2 devise and conduct an experiment to determine the water potential of the potato tissue guidelines for designing the experiment 1 what biological process is being investigated in this experiment 2 what is the independent variable in this investigation how would you manipulate it. Picture common misconceptions sugar and salt do not move by osmosis cell membranes prevent them entering or leaving the cell try this a potato was set up as shown in the figure below (left-hand side) the investigation was left for several hours the results are shown on the right-hand side of the figure picture 1.
Two methods to investigate osmosis and the water potential of a potato cell, including the standard measurement by weighing and the more visual, but challenging, chardakov method. (left) for determination of solute potential by measuring the degree of incipient plasmolysis l practical work select the image (left) for investigation into change in mass or length the water potential of the bathing solution is equal to that of the tissue a tissue beetroots, swede, turnip, parsnip and carrot are suitable. An increasing number of investigators are becoming interested in seed biology with the objective of understanding and controlling aspects of seed germination and seedling establishment the opportunity to increase germination rates as well as improve seedling stands and yields has inspired investigation into the.
The wetland species studied could germinate to any great extent at low soil water potentials in contrast some species this investigation studied the germination response in relation to i/r^^^^ of several wild british species from a range of habitats contrasting in soil water status soil water potential and seed germination. Response of water potentials in pine seedlings to increased soil moisture stress has been studied previously shoot and root water potentials and the response of root water potential of p radiata and p brutia to increasing discussion in a previous investigation, the drought tolerance of p radiata was found to be. Decreased to less than 01 microliter per liter at negative water potentials osmotic inhibition of germination at -4 bars lant of seed germination, andas a potential tool in weed control soil injections of ethylene have c again,we used the less dormant seed lot a to investigate interaction between ethylene and continuous.
The lethal water potential (ψlethal) correlated with stem p99 (ie, the xylem water potential at 99% loss of hydraulic conductivity, plc) of cambium tissue and mortality of cambial cells are proposed to provide an alternative approach to investigate the point of no return associated with plant death.
Activity 2: investigating different water potentials on plant cells • activity 3: investigating water potential of swede • activity 4: effect of temperature on diffusion rate • activity 5: investigating the rate of diffusion through a membrane • activity 6: investigating osmosis in an artificial cell • activity 7: serial dilutions ocr scheme. Free essay: investigate the rate of osmosis in different vegetables (carrot, potato, swede, parsnip and sweet potato) in this coursework experiment i plan to. The water potential of a plant tissue can be determined by the following principle if the tissue shows no net gain or loss of water when immersed in a solution of known molarity, its water potential is equal to that of the external solution samples of the tissue are allowed to come to equilibrium in a range of solutions of. Swede grey/black turned orange turned dark orange analysis: the aim of the experiment was to find out the water potential of swede and potato tissues main factors which affect osmosis are: pressure temperature surface area solute concentration plant tissue we will be investigating solute concentration as this is.
