Aim to investigate water relations in two plant tissues

ANALYSIS There are four basic shipway in which molecules hind end move from one plain to another. They are: ·Diffusion ·Osmosis ·Active hold · deal Transport In this experiment we are looking at osmosis. To be subject to analyse and explain this experiment, we have to know what osmosis is. Osmosis is the drift of molecules from an world of higher body of piddle electric potential, to an area of lower peeing potential through a part permeable membrane. At slightly point, the molecules will be live on either place of the membrane. This is known as the molecules being in balance wheel. A interpretation of offset is the represent where a tissue neither gains, or losses their agglomerate. So, the water potential of the tissue, is the same as the water potential of the resolvent. How concentrate a solution is will accomplishment the mass of the tissue. For this experiment, I found that the general rule was the much concentrated the solution, the ma ss of the tissue started to decrease. In this experiment we can hit stunned when the tissues, potato and swede are in equipoise by plotting our results on a graph. Then by victimization a caper of lift out fit, we can estimate when the simple eye crosses the x-axis. From my results, I know that at some point mingled with 0.2 moles and 0.

4 moles, the potato was in equilibrium. Using a line of take up fit, I can estimate when the potato was in equilibrium. It was estimated that this was reached at 0.22 moles. At some point between 0.6 and 0.8, the swede was in equilibrium. Again, by using a line of best fit, it wa s estimated that equilibrium was reached at ! 0.64 moles. Below is a table of what the concentration of solution (moles) has been transferred into water potential (Kpa). This was done...
