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 chemical bonds between atoms change during photosynthesis. photosynthesis uses light energy to produce food molecules. the reactants of photosynthesis are made of different types of atoms than the products.

Explanation:

1. Food indeed provides energy - rich molecules broken down in cells for energy.
2. In photosynthesis, chemical reactions occur which change the chemical bonds between atoms.
3. Photosynthesis captures light energy and uses it to synthesize food molecules like glucose.
4. According to the law of conservation of mass, the types of atoms in the reactants of photosynthesis are the same as in the products.

2. The chemical bonds between atoms change during photosynthesis. - True
3. Photosynthesis uses light energy to produce food molecules. - True
4. The reactants of photosynthesis are made of different types of atoms than the products. - False
