Question

based on what you have learned about photosynthesis, select the true statements. food provides an organism with energy - rich molecules, which are broken down in cells. the reactants of photosynthesis are made of different types of atoms than the products. the chemical bonds between atoms change during photosynthesis. photosynthesis uses light energy to produce food molecules.

Explanation:

• Food contains energy - rich molecules like carbohydrates which are metabolized in cells for energy.
• In photosynthesis, atoms are rearranged (chemical bonds change) but the types of atoms in reactants and products follow the law of conservation of mass and are the same.
• Photosynthesis is a chemical process where light energy is used to convert carbon - dioxide and water into glucose (food molecule) and oxygen.

Answer:

• Food provides an organism with energy - rich molecules, which are broken down in cells.
• The chemical bonds between atoms change during photosynthesis.
• Photosynthesis uses light energy to produce food molecules.
