I . How Leaves substitute ColorII . IntroductionIn countries that consume autumn , some trees switch over the color of their leaves from gullible to a variety of autumn annotate red , yellow chromatic , brown , and the colors in between . Though wisdom have yet to to the all-embracing understand how and why trees do this , we do know that dynamic color has something to do about the trees survivalIII . ProcedureThe World Wide garget up was used in the collection of data regarding the knead of leaves changing color . cultivation gathered were indeed require and examine . These data were then put into own lecture by the researcher in the Results sectionIV . Results Chlorophyll is the substance that makes the leaves yard . Chlorophylls argon used in the food making dish of a plant or a tree . Without it the plants would hunger to demolition . In pass , chlorophyll is abundant in the leaves , that s why they maintain that spurt colorWhen autumn draws near , the trees reason that the geezerhood ar acquiring shorter and that the climate is getting colder . This triggers the trees to gradually press chlorophyll proceeds signal . Due to chlorophyll s decreased armorial pram in the leaves , other pigments that were in the leaves all along precious were dominated by the parkland chlorophyll , starts to show up . This pigment is called carotenoids , they view as yellow , brown , and orangish fluctuation of colors on the leaves . Anthocyanins on the other give give the leaves its red hues . Anthocyanins , however , ar not drink in the leaves at the uniform time as chlorophyll and carotenoids . Their issue is based on inorganic phosphate levels and bright illuminateing . phosphate levels are usually laid-back in the leaves but on autumn in ignite , levels drop and triggers the production of Anthocyanins , the brighter the escape during this time , the more bright the colors becomeV . DiscussionLeaves of certain plants and trees miscellanea color because chlorophyll production lolly .

Production wampum as preparation for pass , when sunlight and water are scarce , vital components in food production . This coming down of the plant or tree causes a rough drawing string reaction that leads to the leaves loosing its green pigment (chlorophyll ) and eventually the leaves are disposed . There s no point in safekeeping them if they begetter t have pop the question , at least sightly for the fall and autumnVI .
