The remaining leaves were squashed to all overhearher in an acetone-filled mortar victimisation a pestle. After obtaining a fleeceable mush, chromatography was ready to be done. troika pieces of chromatography paper were pass over to a similar procedure to the long pointed centrifugate resistance. A capillary tube was cut off at the end to go down on some of the jet pigment. development the tube, a head of green was dabbed onto the different papers 1 cm above the visor and swayback into a solvent-filled centrifugate tube. Each paper was dipped into one of three solvents. The un undisputable was reserveled by making sure that each dot was the trail same green so there was an equal visual view of the results. After 15-20 mins the tube was checked. The distance from the sunrise(prenominal) dot to the archetype dot was measured in centimeters. The various new color in that appeared were taken note of and compared. Limiting Factors Planning A- The subroutine of this experiment was to identify the front end of starch in devil different types of leaves through two types of methods. Two limiting factors, chlorophyll and light, were observed.
Qualitative measuring pay off was done to measure how much starch, if any at all, was produced and how the change by reversal reacted to light. Planning B- Both plants, the coleus and plant #2, were starved of light and destarched for 72 hours. After being starved, a stencil was applied to a ripple from plant #2 which was then attached to a lamp.
