1. Capturing Sunlight: Trees use chlorophyll, a green pigment in their leaves, to capture sunlight.
2. Taking in Carbon Dioxide: Trees absorb carbon dioxide from the air through tiny pores on their leaves called stomata.
3. Using Water: Water is absorbed from the soil through the roots and transported up to the leaves.
4. Creating Sugar: With sunlight, carbon dioxide, and water, trees perform a chemical reaction. This converts these ingredients into glucose, a simple sugar, and oxygen.
5. Growth and Energy: The glucose produced is the tree's food source. It provides energy for:
* Building new cells: This allows the tree to grow taller, wider, and develop new branches, leaves, and roots.
* Repairing damage: The tree can use the glucose to repair any damaged parts.
* Storing energy: Excess glucose can be stored as starch for later use.
6. Releasing Oxygen: The by-product of this process is oxygen, which is released back into the atmosphere.
In summary: Photosynthesis is the foundation for tree growth. It allows them to produce their own food source and energy, enabling them to build new tissues and expand their structure. This process is vital for the tree's entire life cycle.
