Which gas in the air is used by plants for photosynthesis?a)Nitrogenb)...
Understanding Photosynthesis
Photosynthesis is a vital process carried out by plants, where they convert light energy into chemical energy. This process is essential for life on Earth, as it produces oxygen and organic compounds that serve as food for various organisms.
The Role of Carbon Dioxide
Plants require specific components to perform photosynthesis, and one of the key gases involved is carbon dioxide (CO2). Here’s how it works:
Importance of Oxygen and Other Gases
While oxygen is a byproduct of photosynthesis and nitrogen is abundant in the atmosphere, they are not utilized directly in this process. The main gas that plants need for photosynthesis is indeed carbon dioxide.
In summary, carbon dioxide is essential for plants to produce food and oxygen through photosynthesis, supporting life on Earth. Understanding this process highlights the importance of maintaining healthy plant ecosystems for our environment.

The Role of Carbon Dioxide
Plants require specific components to perform photosynthesis, and one of the key gases involved is carbon dioxide (CO2). Here’s how it works:
- Intake of Carbon Dioxide: Plants absorb carbon dioxide from the atmosphere through tiny openings in their leaves called stomata.
- Light Energy Absorption: Chlorophyll, the green pigment in plants, captures sunlight, providing the energy needed for the process.
- Water Utilization: Water absorbed by the roots also plays a crucial role in photosynthesis.
- Production of Glucose: Using sunlight, carbon dioxide, and water, plants convert these inputs into glucose (a type of sugar) and oxygen. The formula for photosynthesis can be simplified as:
C6H12O6 (glucose) + O2 (oxygen) produced from CO2 and H2O in the presence of sunlight.
Importance of Oxygen and Other Gases
While oxygen is a byproduct of photosynthesis and nitrogen is abundant in the atmosphere, they are not utilized directly in this process. The main gas that plants need for photosynthesis is indeed carbon dioxide.
In summary, carbon dioxide is essential for plants to produce food and oxygen through photosynthesis, supporting life on Earth. Understanding this process highlights the importance of maintaining healthy plant ecosystems for our environment.
