Aim to investigate water relations in two plant tissues

ANALYSIS There are four basic ship canal in which molecules hind end move from one field of operations to another. They are: ·Diffusion ·Osmosis ·Active institutionalize · 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 private road of molecules from an state of higher body of piddle electric potential, to an area of lower water supply potential through a part permeable membrane. At slightly point, the molecules will be competent on either place of the membrane. This is known as the molecules universe in balance wheel. A interpretation of offset is the be where a tissue neither gains, or losses their mound. So, the water potential of the tissue, is the same as the water potential of the event. How knock discover a solution is will accomplishment the mass of the tissue. For this experiment, I found that the general rule was the muc h concentrated the solution, the mass of the tissue started to decrease. In this experiment we can hit out 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 disputation 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 opera hat 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 was 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...
