(mÄth'Än') A colorless, odorless, flammable gas that is the simplest hydrocarbon. It is the major constituent of natural gas and is released during the decomposition of plant or other organic compounds, as in marshes and coal mines. Methane is the first member of the alkane series.
Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules (e.g., sugars). Photosynthesis powers almost all trophic chains and food webs on the Earth.
Process of Photosynthesis. During photosynthesis, the energy from sunlight is broken down with carbon dioxide and water to form ATPs (adenosine triphosphate). ATPs are then used to power reactions in the cell that produce glucose, the primary sugar used to fuel the cell's activities.The light used in the reaction for photosynthesis is absorbed by chlorophyll, an organelle in the cell, that is able to take in red or blue light.TPs are then used to power reactions in the cell that produce glucose, the primary sugar used to fuel the cell's activities.
