Detailed explanation-1: -As chlorophyll goes away, other pigments start to show their colors. This is why leaves turn yellow or red in fall. In fall, plants break down and reabsorb chlorophyll, letting the colors of other pigments show through.
Detailed explanation-2: -When the temperatures in the autumn season begin to drop, the air becomes colder. During this season, the amount of sunshine falls and the production of the chlorophyll pigment in the leaves decreases until it completely stops. Consequently, the leaves change to a yellow or red color.
Detailed explanation-3: -Leaves change color during the autumn because the amounts of pigments change as the leaves prepare to fall from the trees. All leaves gradually lose chlorophyll during the growing season, and this loss accelerates before leaf fall.
Detailed explanation-4: -As day length shortens and temperatures cool, hormones within the plant are activated to begin the abscission process. Chlorophyll production stops and the pigment starts to degrade, often revealing showy reds and yellows that were masked by green.
