急!急!急!急!急!急!about光合作用

Photosynthesis is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the "fuel" used by all living things. The conversion of unusable sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll. Most of the time, the photosynthetic process uses water and releases the oxygen that we absolutely must have to stay alive.

1.植物的葉綠素會在陽光下與空氣中的二氧化碳和水份產生光合作用，製造出來的物質是醣和氧氣。
2. 醣是植物生長需要的養份，氧氣則會經葉片上的氣孔回到空氣中。所以多種植物，可令空氣清新。
