1. Photosynthesis: A plant, like a carrot, takes in carbon dioxide from the air through tiny openings called stomata on its leaves.
2. Energy from Sunlight: The plant uses energy from sunlight to power a chemical reaction within its chloroplasts (the plant's energy factories).
3. Conversion to Sugar: The plant uses the energy from sunlight and the carbon dioxide to convert it into a simple sugar called glucose (C6H12O6). This process is called photosynthesis.
4. Glucose to Starch: The plant uses the glucose for energy or stores it as starch. Starch is a complex carbohydrate made up of many glucose molecules linked together.
5. Carrot Growth: The carrot stores starch in its root, where it serves as a reserve food source. This stored starch helps the carrot to grow and develop.
In summary: The carbon atom from the carbon dioxide molecule is incorporated into a glucose molecule during photosynthesis. The glucose molecules are then linked together to form starch, which is stored in the carrot root.
Here's the simplified chemical equation for photosynthesis:
6CO2 + 6H2O + light energy → C6H12O6 + 6O2
* CO2: Carbon dioxide from the air
* H2O: Water absorbed from the soil
* Light energy: Energy from the sun
* C6H12O6: Glucose (sugar) produced by the plant
* O2: Oxygen released into the air
