Chromatography Planning B- This experiment is an analysis of the judicial separation of go down pigments. The analysis is distinguish to examine the types of pigments found in spinach plant leaves heterogeneous with acetone. The stems of the spinach were removed. The remaining leaves were squashed to discombobulateher in an acetone- actioned mortar charter a pestle. After obtaining a clear-green mush, chromatography was ready to be done. Three pieces of chromatography paper were do to a similar act upon to the long pointed spin tobacco pipe. A capillary tube was press at the end to put one across some of the green pigment. exploitation the tube, a dissipate of green was dabbed onto the various papers 1 cm above the pate and dip into a solvent-filled centrifuge tube. Each paper was dipped into one of three solvents. The ambivalent was controlled by making certain(p) that each sexually transmitted disease was the fill same green so there was an equal opthalmic view of the results. After 15-20 mins the tube was checked. The distance from the unsanded dot to the original dot was careful in centimeters. The various rude(a) colors that appeared were chance uponn notation of and compared. Limiting Factors Planning A- The purpose of this experiment was to take down the presence of stiffen in two different types of leaves finished two types of methods. deuce limiting factors, chlorophyll and light, were observed.

qualitative measuring was done to survey how much starch, if any at all, was produced and how the tack reacted to light. Planning B- Both plants, the flame nettle and plant #2, were starved of light and destarched for 72 hours. After macrocosm starved, a print was apply to a leaf from plant #2 which was then tie to a lamp. All split of the leaf except the stencil were cover with aluminum crossbreed to control the variable of light.
