What is the name of the process that converts light energy into chemical energy in plants?

• A. Phototropism
• B. Photosynthesis
• C. Fermentation
• D. Cellular respiration

Answer: (B)

The process that converts light energy into chemical energy in plants is called photosynthesis. During photosynthesis, plants absorb sunlight using chlorophyll in their leaves and use that light energy to convert carbon dioxide from the air and water from the soil into glucose—a type of sugar that serves as food for the plant. Additionally, oxygen is released as a byproduct of this process. Photosynthesis is fundamental for plants and supports life on Earth by providing a primary source of energy for nearly all ecosystems, as well as oxygen for many organisms. This process occurs primarily in the chloroplasts of plant cells, where light energy is harnessed and transformed. In contrast, phototropism refers to the growth movement of plants toward light, while fermentation is a metabolic process that occurs in the absence of oxygen, and cellular respiration is the process by which cells convert glucose into energy using oxygen. Each of these terms describes different biological processes and does not pertain to the specific conversion of light energy into chemical energy that characterizes photosynthesis.
