Question

How is leaves change color related to photosynthesis

Answer 1

Answer: Chlorophyll

Step-by-step explanation:

Photosynthesis takes place because the cells of the leaf contain the pigment chlorophyll, a bright-green pigment that gives leaves their green color. As fall approaches, trees seal off leaves from the rest of the plant in order to prevent water loss from stomata. Once the leaves are sealed off, the leaf stops producing chlorophyll. Additionally, any chlorophyll remaining in the leaves begins to break down. As the chlorophyll degrades in the leaves, the bright green color disappears. With the green pigment gone, the colors of the other pigments within the leaf can finally be seen.

In other words, those beautiful oranges and yellows that we associate with fall leaves are actually present in the leaves all along—they have just been masked by the green chlorophyll. With the chlorophyll gone, their true colors can be seen.

Answer 2

Step-by-step explanation:

Chlorophyll Breaks Down

But in the fall, because of changes in the length of daylight and changes in temperature, the leaves stop their food-making process. The chlorophyll breaks down, the green color disappears, and the yellow to orange colors become visible and give the leaves part of their fall splendor.
