In plant cells, chloroplasts convert energy from the sun into which form of energy stored in molecules during photosynthesis?
A
Thermal energy released as heat to warm the cell
B
Nuclear energy stored in the atom's nucleus
C
Chemical energy stored in sugars (e.g., glucose)
D
Mechanical energy used directly to power cilia movement
검증된 단계별 안내1
Understand the role of chloroplasts in plant cells: Chloroplasts are organelles responsible for capturing light energy from the sun during photosynthesis.
Recall the process of photosynthesis: Chloroplasts convert light energy into chemical energy by synthesizing glucose and other sugars from carbon dioxide and water.
Identify the form of energy stored: The energy captured from sunlight is stored as chemical energy within the bonds of sugar molecules like glucose.
Eliminate incorrect options: Thermal energy is released as heat but is not the main stored energy; nuclear energy relates to atomic nuclei, not photosynthesis; mechanical energy powers movement, which is unrelated here.
Conclude that the energy stored by chloroplasts during photosynthesis is chemical energy in sugars such as glucose.
