Photosynthesis is an important part of the carbon cycle because it removes__________ from the atmosphere and through chemical reactions, rearranges the atoms into other forms of useable carbon molecules for the plant and releases ________ back into the atmosphere.
Photosynthesis is the biochemical reaction by which plants produce complex food molecules (sugars). This process requires an energy input from sunlight to occur. In this reaction, the atmospheric carbon dioxide and water combine to form glucose such as carbon-based organic molecules and oxygen. Photosynthesis is an important part of the carbon cycle because it removes carbon dioxide from the atmosphere and through chemical reactions, rearranges the atoms into other forms of usable carbon molecules for the plant and releases oxygen back into the atmosphere.

To understand how photosynthesis works, we can break it down into its basic components:
1. Sunlight: This is the source of energy for photosynthesis. Sunlight contains packets of energy called photons, which are absorbed by the chlorophyll pigment in plants.
2. Chlorophyll: This green pigment found in plants is responsible for capturing sunlight. It is located in special structures called chloroplasts, which are found in the cells of plant leaves.
3. Carbon Dioxide (CO2): Plants take in carbon dioxide from the atmosphere through tiny openings called stomata, usually present on the undersides of plant leaves. CO2 is a simple molecule consisting of one carbon atom bonded to two oxygen atoms.
4. Water (H2O): Plants absorb water through their roots from the soil. Water molecules consist of two hydrogen atoms bonded to one oxygen atom.
5. Photosynthesis reaction: In the presence of sunlight and chlorophyll, plants convert carbon dioxide and water into glucose (a simple sugar), as well as other carbon-based organic molecules. The overall equation for photosynthesis is:
6CO2 + 6H2O + sunlight → C6H12O6 (glucose) + 6O2
In this equation, carbon dioxide and water react in the presence of sunlight to produce glucose and oxygen.
6. Carbon cycle: Photosynthesis is a crucial part of the carbon cycle, which involves the movement of carbon through various forms in the environment. Photosynthesis helps remove carbon dioxide from the atmosphere, reducing its concentration and mitigating its impact on climate change. Additionally, through photosynthesis, plants convert the carbon atoms from carbon dioxide into glucose and other organic molecules, which are then used as building blocks for plant growth. Oxygen, a byproduct of photosynthesis, is released into the atmosphere for other organisms to breathe.
Understanding photosynthesis gives us insight into the importance of plants in maintaining the balance of atmospheric gases and their role in sustaining life on Earth.
