When the abscission layer of a plant grows, it cuts off the circulation of nutrients, sugar and water to the leaves, which causes the chlorophyll that gives the plant its green color to disintegrate and makes carotene sh... More »

Sunlight and water both support the production of chemical nutrients inside the cells of a plant. Sunlight is critical in the process during which water molecules are broken apart inside the pigmented cells of the plant.... More »
