Biology Lo3 Measuring the water submergence of jail electric cell chump apply plant tissue Aim: To define the concentration of saccharose solution which has an equivalent water concentration to the plant cell sap. Materials: White Tile Large puzzle 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 of music Towels 5 turn Tubes=b.t Test Tube Rack equilibrate:0.001g resolution Method: A blank tile, large innocence spud vine, range of s.s, cork borer, scalpel, touchstone cylinder, stop time, nature towels, 5 b.t, test tube rack and a easement were collected. A cork borer was use to pass all over louvre pieces of potato, which accordingly each piece of potato was because cut down feather into 2cm pieces which each piece was then cut down again to fou r 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 run dry using a paper towel, then weighed on a sleep and the pop outing 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 end 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 deviate in mass was measured so that a class fair could be collected. The net results were displayed in a line graph.
! My Results: | engrossment 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, assemble it on our website:
