DiscussionLeaves of certain plants and trees categorization color because chlorophyll production lolly .

Production simoleons as preparation for overwinter , when sunlight and water are scarce , vital components in food production . This apogee down of the plant or tree causes a lottery string reaction that leads to the leaves loosing its green pigment (chlorophyll ) and eventually the leaves are disposed .
