Biology Lo3 Measuring the water niggardliness of jail jail cell chump apply plant tissue Aim: To meet the concentration of saccharose solution which has an equivalent water concentration to the plant cell sap. Materials: White Tile Large rostrum spud Range of sucrose solution=s.s (0.1M,0.2M,0.3M,0.4M,0.5M) plug stone drill (8mm) Scalpel Ruler Measuring Cylinder Stop Clock wallpaper Towels 5 turn Tubes=b.t Test Tube Rack fit:0.001g resolution Method: A blank tile, large bloodless potato vine, range of s.s, cork borer, scalpel, measuring stick cylinder, stop time, composition towels, 5 b.t, test tube rack and a assuagement were collected. A cork borer was use to pass everyplace louvre pieces of potato, which indeed each piece of potato was hence cut down feather into 2cm pieces which each piece was then cut down again to four pie ces. 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 teetotal using a paper towel, then weighed on a sleep and the fetching 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 holy 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 similar table as before. Then the percentage switch over in mass was measured so that a class amount could be collected. The net results were displayed in a line graph. My Results: | constriction 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, company it on our website: OrderCustomPaper.com
