Nitrogen

What is The reason that deciduous leaves turn colors of red and yellow in the fall is?

Deciduous leaves turn red and yellow in the fall due to the breakdown of chlorophyll, which reveals other pigments present in the leaves such as carotenoids (yellow) and anthocyanins (red). As the days get shorter and temperatures drop, the tree stops producing chlorophyll, allowing these other pigments to show through.

When it gets colder what does chlorophyll do?

Slows down and eventurally stops. That is why in the fall leaves turn yellow and other pretty shades and eventurally fall off the tree because they are not producing and sugar (glucose) for the tree so they are no longer needed

Where do the red orange yellow brown and purple color come from when the leaves begin to change in the fall?

The vibrant colors of red, orange, yellow, brown, and purple in fall leaves result from the breakdown of chlorophyll, the green pigment responsible for photosynthesis. As days shorten and temperatures drop, chlorophyll production slows and eventually stops, revealing other pigments in the leaves. Carotenoids produce yellow and orange hues, while anthocyanins create red and purple shades, often formed in response to sunlight and cooler temperatures. The combination of these pigments, along with the remaining chlorophyll, creates the stunning fall foliage we admire.

Is leaves turning color in the fall a chemical or physical change?

I don't know the scientific equation, but I do know that the tree withdraws it's sugars from the leaves, during the autumn and winter to make sure that there is enough for the main tree. The withdrawal of the sugars is a physical action, but it is a chemical one as well. The chlorophyll that was made thru the sunlight on the leaves for photosynthesis. This stops when the weather turns colder and there is less sunlight causing the leaves lessen the amount to chlorophyll they can make, signaling to the tree to cut off the sugar supply to the leaves. I'd say it's both. Also, You have witnessed a spectacular chemical change if you have seen the leaves on a tree change from green to bright yellow, red, or orange. But, it is not a change from a green pigment to a red pigment, as you might think. Pigments are chemicals that give leaves their color. In autumn, however, changes in temperature and rainfall amounts cause trees to stop producing chlorophyll. The chlorophyll already in the leaves undergoes a chemical change into colorless chemicals.Where do the bright fall colors come from? The pigments that produce fall colors have been present in the leaves all along. However, in the summer, chlorophyll is present in large enough amounts to mask these pigments. In the fall, when chlorophyll production stops, the bright pigments become visible.
