B
Sound energy
C
Light energy
D
Mechanical energy
Verified step by step guidance1
Understand the process of photosynthesis: Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy stored in glucose molecules.
Identify the role of chloroplasts: Chloroplasts are specialized organelles in plant cells that contain chlorophyll, a pigment responsible for capturing energy from sunlight.
Determine the type of energy involved: Photosynthesis specifically requires light energy, which is absorbed by chlorophyll molecules in the chloroplasts.
Eliminate incorrect options: Thermal energy (heat), sound energy, and mechanical energy are not involved in the photosynthesis process.
Conclude that the correct answer is light energy, as it is the type of energy captured by chloroplasts during photosynthesis.
