As a branch of astronomy, star formation includes the study of the interstellar medium (ISM) and giant molecular clouds (GMC) as precursors to the star formation process, and the study of protostars and young stellar objects as its immediate products.
Carbon capture and storage (CCS) (or carbon capture and sequestration) is the process of capturing waste carbon dioxide (CO2) from large point sources, such as fossil fuel power plants, transporting it to a storage site, and depositing it where it will not enter the atmosphere, normally an underground geological formation.
The main source of carbon for plants comes from the atmosphere as carbon dioxide and fixation of this carbon dioxide by leaves and other. green parts of the shoot system in the presence of light as an energy source - the process of photosynthesis. Some of this fixed carbon is. converted into fuels for respiration, such as glucose, some is stored as compact materials like starch, and some is used in building blocks, such as proteins, nucelotides and phospholipids, to build the plant body. Fixation is an odd word, and one that stems all the way back to alchemy. It makes perfect sense, however, when you think of gases as. mobile, with their molecules constantly moving around by diffusion due to their thermal kinetic energy.
