In the ~2.5 billion years since photosynthetic organisms have appeared daily in this performance, enough oxygen has accumulated to account for 21% of the atmosphere...
Photosynthesis is a process used by plants in which energy from sunlight is used to convert carbon dioxide and water into molecules needed for growth. These molecules include sugars, enzymes and chlorophyll.
What are the conditions for photosynthesis - eschooltoday
Photosynthesis results in an increase in ; i.e. there is more carbohydrate in the plant. They can turn some of the glucose into fat or protein. They have to make lots of different chemicals to grow, but the two most important ones are fats and proteins. To do this they need energy (growth requires energy from glucose). Plants also have to make a very special chemical called DNA: this is the hereditary chemical of all animals and plants. They must also make lots of new chlorophyll.
