What process do green plants use to convert light energy into chemical energy?

• A. Respiration
• B. Photosynthesis
• C. Fermentation
• D. Evaporation

Answer: (B)

Green plants use photosynthesis to convert light energy into chemical energy. During this process, plants capture sunlight using chlorophyll, the pigment found in their leaves. The light energy is then utilized to convert carbon dioxide from the air and water from the soil into glucose, a simple sugar that serves as food for the plant. This process also produces oxygen as a byproduct. Photosynthesis is essential for life on Earth since it is the primary means by which energy from the sun is captured and stored in a form that can be used by living organisms. The overall reaction can be summarized by the equation: \[ 6CO_2 + 6H_2O + light \ energy \rightarrow C_6H_{12}O_6 + 6O_2 \] This illustrates how carbon dioxide and water, in the presence of light energy, result in glucose and oxygen. The glucose produced is not only a vital energy source for the plant itself but also serves as the foundation of the food web, supporting a myriad of life forms—thus, emphasizing the importance of photosynthesis in ecosystems.

Photosynthesis is essential for life on Earth since it is the primary means by which energy from the sun is captured and stored in a form that can be used by living organisms. The overall reaction can be summarized by the equation:

[ 6CO_2 + 6H_2O + light \ energy \rightarrow C_6H_{12}O_6 + 6O_2 ]

This illustrates how carbon dioxide and water, in the presence of light energy, result in glucose and oxygen. The glucose produced is not only a vital energy source for the plant itself but also serves as the foundation of the food web, supporting a myriad of life forms—thus, emphasizing the importance of photosynthesis in ecosystems.
