Osmosis Aim: To determine the concentration of cell sap in a potato cell. Osmosis is the movement of water through a semi-permeable membrane. It starts from a weak solution and becomes a more stronger solution until the concentrations on both sides are equal. To investigate the range of solutions needed to find the point at which the surrounding solution is the same as the cell sap in the vacuole.

. Potato crops were the best option for Irish people because potatoes provide lots of nutrients and the crops were easy to grow in Irish lands due to their adaptability in almost any surface. However‚ the dependency on potatoes started to be dangerous when a new potato disease commonly known as potato blight affected the crops year after year in the 1840’s. This disease caused the loss of great part of the crops until the end of the decade‚ but especially in the year 1847‚ called the black forty-seven

of salt concentration on potatoes. Scope In this investigation three square pieces of potato were placed into individual beakers containing different salt concentrations of 0%‚ 10% and 20% and observed for 120min. Hypothesis The theory behind this experiment was that the piece of potato placed into the 0% salt solution would increase in weight and size as it is a hypertonic solution. The pieces of potato placed into the 10% and 20% salt solution would theoretically decrease in weight and size
