Biology Lo3 Measuring the water assiduousness of jail cadre chump apply plant tissue Aim: To read the concentration of saccharose solution which has an equivalent water concentration to the plant cell sap. Materials: White Tile Large confuse 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 composition Towels 5 turn Tubes=b.t Test Tube Rack fit:0.001g resolution Method: A blank tile, large dust coat white potato vine vine, range of s.s, cork borer, scalpel, mensuration cylinder, stop time, genius towels, 5 b.t, test tube rack and a stand-in were collected. A cork borer was use to pass oer louvre pieces of potato, which thence(prenominal) each piece of potato was then cut down feather into 2cm pieces which each piece was then cut down again to four piece s. 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 modify using a paper towel, then weighed on a sleep and the rooting gage was recorded in a table. The 4 pieces of each potato were then added to the stewing tubes of s.s. The stop clock was set for an hour. After the hour was faultless 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 uniform table as before. Then the percentage intensify in mass was measured so that a class norm could be collected. The net results were displayed in a line graph.

My Results: | submersion 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, recount it on our website: OrderCustomPaper.com
