Biology Lo3 Measuring the water constriction of jail kiosk chump apply plant tissue Aim: To look the concentration of saccharose solution which has an equivalent water concentration to the plant cell sap. Materials: White Tile Large stamp spud Range of sucrose solution=s.s (0.1M,0.2M,0.3M,0.4M,0.5M) plug rock drill (8mm) Scalpel Ruler Measuring Cylinder Stop Clock piece Towels 5 turn Tubes=b.t Test Tube Rack parallelism:0.001g resolution Method: A blank tile, large whiteness stump spud vine, range of s.s, cork borer, scalpel, measuring cylinder, stop time, story towels, 5 b.t, test tube rack and a persist were collected. A cork borer was use to pass everywhere louvre pieces of potato, which and then(prenominal) 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 cylinder was used to measure 10ml of each s.s individually, which were then added to the b.ts. The potato pieces were dabbed juiceless using a paper towel, then weighed on a sleep and the divideing gage was recorded in a table. The 4 pieces of each potato were then added to the turn tubes of s.s. The stop clock was set for an hour. After the hour was perfect 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 same(p) table as before. Then the percentage diverge in mass was measured so that a class add up could be collected. The net results were displayed in a line graph.

My Results: | tautness 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, ball club it on our website: BestEssayCheap.com
