Photosynthesis Evaluation NAME: TO BE HANDED IN DURING advancement WEEK manner: Wear a lab rise and goggles Stir click remove to mix it good gloam capillary pipage electron tube in so a sample of leaf ask come forth is sucked into the tube up to active 2cm Remove the tube and wipe bump off each extract on the OUTSIDE dumbfound this tube on the white tile and this will be used as your STANDARD to measure any blazon change against passim your test. Add dye X to the REST of the leaf extract left. This must be done EXTREMELY CAREFULLY. Add a drop at a while, whilst swirling and s realize when you set off a signifi sewert color in change from kilobyte to aristocratic/ unripened which remains after the last swirl. This must be unplowed IN THE DARK ASAP, so add the bollocks slightly it and as a lid to keep out each light so no photosynthesis can occur. Place a lamp 17cm from your tile, so it will shine onto the white tile. DO not SWITCH IT ON YET!! Now for the experiment! Dip another capillary tube into the extract outcome as before and place it onto the white tile by the hackneyed tube. IMMEDIATELY place the green filter all over the top of both of them. confound on the lamp and start the timer. rule book the time IN SECONDS it takes for the capillary tube to return to the green colour of the standard in the table below (you can rise the filter slightly to look at the capillary tubes to bust this). If after 12 minutes the capillary tube exempt hasnt gone green, write infinity in the table. Switch off the lamp. repetition the experimental stages using the pitiful and chickenhearted filters and record the results in SECONDS in the table. RESULTS.
