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 occurs in a specific organelle that contains pigments like chlorophyll to capture light energy.
Understand that lysosomes are involved in digestion and recycling of cellular waste, not photosynthesis.
Recognize that the rough endoplasmic reticulum is involved in protein synthesis and processing, not photosynthesis.
Know that mitochondria are the site of cellular respiration, which generates energy from food, but do not perform photosynthesis; therefore, the organelle responsible for photosynthesis is the chloroplast.
