A Change Of Color In The Fall. 5 How do different wavelengths affect plant growth. During winter theres not enough water or light for photosynthesis to take place.

There are three different types of pigment involved in Fall colors the first of which is chlorophyll which gives leaves their verdant green color. In the fall plants break down and reabsorb the chlorophyll that is in them. Chlorophyll gives a green color to the leaf.

Other colors are absorbed by chlorophyll for photosynthesis. When this happens it is harder for the chlorophyll in the leaves to make the food needed to stay green. But in the fall because of changes in the length of daylight and changes in temperature the leaves stop their food-making process.

There is a lot of sunlight in the summer. While leaves changing color. As the season changes temperatures drop and days get shorter.

The lack of chlorophyll reveals yellow and orange pigments that were already in the leaves but masked during the warmer months.
