Hi Zeenat,

Plants produce two very important gases that compose the atmosphere - oxygen (during the daylight) and carbon dioxide (at night). The oxygen plants produce is very important and insures life on Earth can exist. That's why plants are often times called the "lungs of the Earth".

Thanks for the great question,
