Photosynthesis process removes carbon dioxide from the atmosphere. Green plants remove carbon dioxide from the atmosphere by photosynthesis. 

The level of carbon dioxide in the atmosphere is maintained by several processes, including photosynthesis, respiration and combustion. 

Ribosomes are the sites where proteins are synthesised. The transcription process where the code of the DNA is copied occurs in nucleus but the main process of translating that code to form other protein occurs in ribosomes.
