Ribosomes
Breakdown or degradation of molecules primarily takes place in the lysosomes, which contain enzymes that can break down various biomolecules such as proteins, lipids, and nucleic acids into their constituent parts for recycling or disposal.
In eukaryotic cells, the organelles that do this are called 'mitochondria.' However, there are other pathways to create energy that exist outside of mitochondria and take place in other parts of a cell. To learn more, look up 'glycolysis'.
Catabolism is the process of breaking down molecules into smaller parts to release energy. Catabolism takes place in the mitochondria of the cell.

The Cytoplasm
Photosyntesis takes place in the chloroplasts.
The organelle in which photosynthesis takes place is called the chloroplast. It contains chlorophyll, a pigment that captures light energy for the process of photosynthesis.
Glycolysis takes place in the cell cytoplasm
