This cell division is called mitosis, and it takes place during the last four phases of the cell life cycle: Prophase,Metaphase, Anaphase, and Telophase. The purpose of mitosis is to copy the genetic material so that whenTelophase has ended, the result is two genetically identical cells.
CO2 in the atmosphere decreases during the growing season and increases during the rest of the year, which leads to maximum buildup in April and May before photosynthesis begins to take over again.
There's more carbon dioxide in the winter and a bit less in the summer. That's the collective breathing of all the plants in the Northern Hemisphere. "Plants are accumulating carbon in the spring and summer when they're active, and they're releasing carbon back to the air in the fall and winter," Graven explains.
Only the non-covalent bonds like hydrogen bonds which give it's functional shape.
