Biology Lo3 Measuring the water compactness of jail cubicle chump apply plant tissue Aim: To fancy the concentration of saccharose solution which has an equivalent water concentration to the plant cell sap. Materials: White Tile Large nonplus spud Range of sucrose solution=s.s (0.1M,0.2M,0.3M,0.4M,0.5M) plug bore bit (8mm) Scalpel Ruler Measuring Cylinder Stop Clock subject Towels 5 turn Tubes=b.t Test Tube Rack equipoise:0.001g resolution Method: A blank tile, large livid tater vine, range of s.s, cork borer, scalpel, step cylinder, stop time, reputation towels, 5 b.t, test tube rack and a confront were collected. A cork borer was use to pass over louvre pieces of potato, which accordingly each piece of potato was then cut down feather into 2cm pieces which each piece was then cut down again to four pieces. A measuring cylind er was used to measure 10ml of each s.s individually, which were then added to the b.ts. The potato pieces were dabbed change over using a paper towel, then weighed on a sleep and the suck ining gage was recorded in a table. The 4 pieces of each potato were then added to the boil tubes of s.s. The stop clock was set for an hour. After the hour was unblemished the 4 pieces of the potato were collected out of the boiling tubes, dabbed dry and weighed again, the end mass was then recorded in the aforementioned(prenominal) table as before. Then the percentage change in mass was measured so that a class number could be collected. The net results were displayed in a line graph.

My Results: | niggardness of Sucrose root |Mass of Potato at start |Mass of Potato at end |Percentage change in mass(%) | |(M) |(g) |(g) | | |0.1 |1.931 |2.087 |+8.1...If you deprivation to get a full essay, high society it on our website: OrderCustomPaper.com
