I . How Leaves neuter ColorII . IntroductionIn countries that experience downslope , some shoetrees substitute the subterfuge of their leaves from green to a variety of autumn transfigure red , yellow orange , br birth , and the colors in between . Though science have yet to in full understand how and wherefore trees do this , we do fill in that ever- changing color has something to do about the trees survivalIII . ProcedureThe World simple wind vane was used in the collection of selective information regarding the process of leaves changing color . Information gathered were thence read and canvas . These data were then put into own words by the researcher in the Results sectionIV . Results Chlorophyll is the import that makes the leaves green . Chlorophylls argon used in the food devising process of a plant or a tree . Without it the plants would starve to oddment . In summer , chlorophyll is vast in the leaves , that s why they maintain that green colorWhen autumn draws approximately , the trees sense that the long time ar getting shorter and that the humor is getting colder . This triggers the trees to gradually put down chlorophyll switch . Due to chlorophyll s decreased front in the leaves , early(a) pigments that were in the leaves all along just were dominated by the green chlorophyll , starts to show up . This pigment is called carotenoids , they barf yellow , brown , and orange discrepancy of colors on the leaves . Anthocyanins on the other hand give the leaves its red hues . Anthocyanins , however , are not present in the leaves at the same(p) time as chlorophyll and carotenoids . Their doing is based on phosphate levels and bright decreaseing . phosphate levels are usually spunky in the leaves but on autumn in shine , levels drop and triggers the production of Ant hocyanins , the brighter the light during th! is time , the more intense the colors becomeV . DiscussionLeaves of certain plants and trees intensify color because chlorophyll production stops .

Production stops as preparation for wintertime , when sunlight and water are scarce , vital components in food production . This closedown down of the plant or tree causes a range of a function reception that leads to the leaves loosing its green pigment (chlorophyll ) and eventually the leaves are disposed . on that point s no point in keeping them if they take on t have purpose , at least just for the occur and autumnVI .
