\nPhotosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy.
\nA) Potential energy is released to form free energy: This describes processes like respiration (breakdown of glucose to release energy) or combustion, where stored chemical energy (potential) is converted into usable energy (free).
\nB) Free energy is converted into potential energy and stored: In photosynthesis, light energy from the sun (a form of free energy) is absorbed and converted into chemical energy stored in the bonds of glucose molecules (a form of potential energy). This is the fundamental energy conversion process in photosynthesis.
\nC) Food is oxidized to release carbon dioxide and water: This describes respiration, where organic food molecules are broken down in the presence of oxygen to release energy, carbon dioxide, and water.
\nD) Oxygen is taken, and carbon dioxide and water vapour are given out: Plants take in carbon dioxide and water for photosynthesis and release oxygen as a byproduct. Taking in oxygen and giving out carbon dioxide and water is the process of respiration (which plants also do).

\n– Photosynthesis uses light energy (free energy) to synthesize organic compounds (food).
\n– Chemical energy is stored in the bonds of these organic compounds (potential energy).
\n– The process converts light energy into chemical energy.
\n<\/section>\n
\nThe overall equation for photosynthesis is: $6\\text{CO}_2 + 6\\text{H}_2\\text{O} + \\text{Light Energy} \\rightarrow \\text{C}_6\\text{H}_{12}\\text{O}_6 + 6\\text{O}_2$. This shows that carbon dioxide and water, using light energy, are converted into glucose (sugar) and oxygen.
