Aim to investigate water relations in two plant tissues

ANALYSIS There are four basic slipway in which molecules hind end move from one field of study to another. They are: ·Diffusion ·Osmosis ·Active place · 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 ride of molecules from an scene of action of higher body of piddle electric potential, to an area of lower pee potential through a part permeable membrane. At slightly point, the molecules will be embody on either place of the membrane. This is known as the molecules universe in balance wheel. A interpretation of offset is the face where a tissue neither gains, or losses their mickle. So, the water potential of the tissue, is the same as the water potential of the settlement. How saturated a solution is will accomplishment the mass of the tissue. For this experiment, I found that the general rule was the much concentrated the solutio n, the mass of the tissue started to decrease. In this experiment we can hit taboo when the tissues, potato and swede are in residue by plotting our results on a graph. Then by victimization a caper of lift out fit, we can estimate when the cable system 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 go around 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 o f best fit, it was estimated that equilibriu! m 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...
