Source of Carbohydrates for Green Plants
Green plants obtain carbohydrates through the process of photosynthesis, where they convert light energy into chemical energy stored in the form of glucose. Let's delve deeper into the sources of carbohydrates for green plants.

Carbon Dioxide
- Green plants take in carbon dioxide from the atmosphere through tiny pores on their leaves called stomata.
- Carbon dioxide serves as the primary source of carbon for the synthesis of carbohydrates during photosynthesis.

Water
- Green plants absorb water from the soil through their roots.
- Water molecules are split into hydrogen and oxygen during the light-dependent reactions of photosynthesis.
- The hydrogen ions are used to reduce carbon dioxide to form carbohydrates.

Sunlight
- Sunlight is essential for photosynthesis as it provides the energy needed to drive the chemical reactions.
- Chlorophyll, a pigment present in the chloroplasts of green plants, captures sunlight and initiates the process of photosynthesis.

Chlorophyll
- Chlorophyll is responsible for absorbing light energy and converting it into chemical energy.
- It plays a crucial role in the synthesis of carbohydrates by transferring electrons during the light-dependent reactions.

Nutrients from Soil
- Green plants also require essential nutrients such as nitrogen, phosphorus, and potassium from the soil to support the synthesis of carbohydrates.
- These nutrients act as cofactors for enzymes involved in various metabolic pathways, including photosynthesis.
In conclusion, green plants derive carbohydrates primarily from carbon dioxide, water, sunlight, chlorophyll, and essential nutrients from the soil. The intricate process of photosynthesis allows green plants to sustain themselves by producing the carbohydrates necessary for their growth and survival.

They get from CO2 and water through photosynthesis.
