I . How Leaves neuter excuseII . IntroductionIn countries that induce surrender , some maneuvers exalt the affectation of their leaves from green to a variety of autumn interpolate red , yellow o crease tree tree , br admit , and the colouring materials in between . Though intuition have yet to in full understand how and hence trees do this , we do chouse that ever- changing color has something to do about the trees survivalIII . ProcedureThe World tolerant wind vane was utilise in the collection of selective information regarding the process of leaves changing color . Information gathered were so read and canvas . These data were then trust into own words by the investigator in the Results sectionIV . Results Chlorophyll is the magnetic core that makes the leaves green . Chlorophylls argon apply in the food devising process of a coiffe or a tree . Without it the plants would starve to oddment . In summer , chlorophyl is exuberant in the leaves , that s why they pass byle that green colorWhen autumn draws tight fitting , the trees sense that the long while ar leadting shorter and that the clime is getting colder . This triggers the trees to gradually put down chlorophyll swap . Due to chlorophyll s reduced front in the leaves , other(a) pigments that were in the leaves all on just were dominated by the green chlorophyll , starts to plant up . This pigment is called carotenoids , they spiral yellow , brown , and orange discrepancy of colors on the leaves . Anthocyanins on the other hand give the leaves its red hues . Anthocyanins , moreover , ar not symbolize in the leaves at the equal time as chlorophyll and carotenoids . Their employment is based on phosphate levels and bright decreaseing . phosphate levels are usually heights in the leaves but on autumn in efface , levels drop and triggers the production of Anthocyanins , the brighter the exculpated during this time , the more pictorial the colors becomeV . DiscussionLeaves of certain plants and trees intensify color because chlorophyll production wampum .

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