During winter, there is not enough sunlight or water. Trees rest during this time and live on the food they store during the summer. They begin to shut down their food-making factories. As the green chlorophyll disappears from the leaves, we begin to see yellow and orange leaves. ...
Mulch with aged compost across the tops of carrots to prevent green shoulders—that is chlorophyll discoloration of root shoulders–which will leave a bitter taste. Growing tips: Growing Carrots for Flavor. Container growing carrots Standard and large carrot varieties are not a good choice for conta...
Why does chlorophyll reflect green light instead of absorbing it? How does temperature affect soil respiration? Explain the role that stomata play in leaves. What is humidity and how does it affect the weather? Why are sweat glands important?

However, most of the year, we cannot see them under the dominant green chlorophyll. In autumn, a tree begins to dispose of the green pigment into nutrients (which have been stored in the leaves so far) and transfers them to the tree's roots to store until the next spring. When leaves...
Inside each photosystem are many pigment molecules. Two hundred green pigment molecules called chlorophyll make up the majority of these molecules.
