The correct answer is that the Golgi apparatus is involved in the modification and packaging of proteins. This organelle processes proteins synthesized in the endoplasmic reticulum, adding necessary modifications, and then sorts and packages them for transport to their destination. Option A is incorrect because protein synthesis is a function of ribosomes. Option C is incorrect because the breakdown of molecules is typically handled by lysosomes. Option D is incorrect because photosynthesis occurs in chloroplasts, which are specialized organelles in plant cells.

The synthesis of proteins is primarily carried out by ribosomes, not the Golgi apparatus. Ribosomes assemble amino acids into proteins.

The Golgi apparatus is responsible for modifying, sorting, and packaging proteins for secretion or use within the cell. This process is essential for proper protein function and distribution.

The breakdown of lipids and carbohydrates is typically performed by lysosomes and enzymes, not the Golgi apparatus. The Golgi primarily deals with modification and transport.

Photosynthesis occurs in the chloroplasts of plant cells, and is not related to the Golgi apparatus. The Golgi has no role in capturing or converting solar energy.
