Which of the following is the source of energy used by green plants for photosynthesis?
Answer Details
The source of energy used by green plants for photosynthesis is the sun.
Photosynthesis is the process by which green plants use light energy to convert carbon dioxide and water into glucose (sugar) and oxygen. The process occurs in chloroplasts, which are organelles found in plant cells. Chlorophyll, a pigment found in chloroplasts, absorbs light energy from the sun and uses it to power the photosynthesis process.
Therefore, green plants require sunlight to carry out photosynthesis and produce the energy needed for their growth and survival. Without sunlight, the process cannot occur, and plants will not be able to produce the food and energy they need to survive. So, the sun is the ultimate source of energy for green plants.
