Identify the process in question: photosynthesis is the process by which light energy is converted into chemical energy in plants and algae.
Recall that photosynthesis primarily occurs in a specific organelle that contains pigments like chlorophyll, which capture light energy.
Understand that the chloroplast is the organelle responsible for photosynthesis, as it houses the thylakoid membranes where the light-dependent reactions take place.
Recognize that other organelles listed, such as the rough endoplasmic reticulum, Golgi apparatus, and mitochondrion, have different functions unrelated to photosynthesis.
Conclude that the chloroplast is the correct organelle where photosynthesis primarily occurs in plant and algal cells.
