1. Ingredients:
* Sunlight: Plants use the energy from sunlight.
* Carbon Dioxide (CO2): Plants take in CO2 from the air through tiny pores called stomata on their leaves.
* Water (H2O): Plants absorb water from the soil through their roots.
2. The Process:
* Chlorophyll: Plants contain a green pigment called chlorophyll in their leaves. Chlorophyll captures light energy from the sun.
* Light-Dependent Reactions: In the first stage, light energy is used to split water molecules. This releases oxygen (O2) as a byproduct, which is what we breathe. The energy from the split water molecules is stored in special energy carriers called ATP and NADPH.
* Light-Independent Reactions (Calvin Cycle): The energy from ATP and NADPH is used to convert carbon dioxide into glucose (a simple sugar). This process also requires enzymes.
3. The Outcome:
* Glucose (C6H12O6): Glucose is a type of sugar that serves as the plant's food. It provides energy for the plant to grow, reproduce, and perform other life functions.
* Oxygen (O2): Oxygen is released as a byproduct of photosynthesis. It is essential for the survival of most living organisms, including humans.
In summary, plants use sunlight, water, and carbon dioxide to create their own food (glucose) and release oxygen as a byproduct through the process of photosynthesis.
