equation between light intensity and sugar concentration

Aspen propagate primarily by sprouting from an expanding root system, creating groups of trees, or clones, ranging in size from several trees to many acres. The prime example is the early season color change showing the unique characteristic of aspen growth. When chlorophyll disappears from a leaf, the remaining carotene causes the leaf to appear yellow. Carotene persists in leaves even when chlorophyll has disappeared. Carotene is a much more stable compound than chlorophyll. The energy of the light absorbed by carotene is transferred to chlorophyll, which uses the energy in photosynthesis. Carotene functions as an accessory absorber. The light reflected by the leaf appears green. When carotene and chlorophyll occur in the same leaf, together they remove red, blue-green, and blue light from sunlight that falls on the leaf. Carotene is also a large molecule (C40H36) contained in the chloroplasts of many plants. The light reflected from carotene appears yellow. Carotene absorbs blue-green and blue light. Therefore, during summer chlorophyll is continuously broken down and regenerated in the leaves of trees.Īnother pigment found in the leaves of many plants is carotene. The synthesis of chlorophyll in plants requires sunlight and warm temperatures. To maintain the amount of chlorophyll in their leaves, plants continuously synthesize it. This chemical energy drives the biochemical reactions that cause plants to grow, flower, and produce seed.Ĭhlorophyll is not a very stable compound bright sunlight causes it to decompose. In this endothermic transformation, the energy of the light absorbed by chlorophyll is converted into chemical energy stored in carbohydrates (sugars and starches). In chloroplasts, the light absorbed by chlorophyll supplies the energy used by plants to transform carbon dioxide and water into oxygen and carbohydrates, which have a general formula of Cx(H2O)y. Chloroplasts are the site of photosynthesis, the process in which light energy is converted to chemical energy. Instead, they are attached to the membranes of disc-like structures, called chloroplasts, inside the cells. They are not soluble in the aqueous solution that fills plant cells. The molecules of chlorophyll are large (C55H70MgN4O6). Therefore, the light the leaves reflect is diminished in red and blue and appears green. The green pigment in leaves is chlorophyll, which absorbs red and blue light from sunlight. Three things affect fall colors: Length of day/night weather and pigments (there are three categories of pigment that contribute to fall colors).
