The photosynthesis conducted by land plants and algae is the last word source of Strength and organic and natural materials les plantes qui préfère le sol calcaire in nearly all ecosystems. Photosynthesis, at the outset by cyanobacteria and afterwards by photosynthetic eukaryotes, radically changed the composition from the early Earth's anoxic atmosphere, which Because of this is now 21% oxygen.

Green plants present a considerable proportion of the planet's molecular oxygen; the sugars they produce provide the energy for some of Earth's ecosystems, and other organisms, like animals, possibly take in plants instantly or depend on organisms which accomplish that.

Frost and dehydration can harm or get rid of plants. Some plants have antifreeze proteins, heat-shock proteins and sugars inside their cytoplasm that enable them to tolerate these stresses.
