Understand that photosynthesis is the process by which light energy is converted into chemical energy in plants and algae.
Recall that photosynthesis primarily occurs in a specialized organelle that contains pigments like chlorophyll to capture light energy.
Identify the organelle known for containing chlorophyll and being the site of the light-dependent and light-independent reactions of photosynthesis.
Compare the options: mitochondrion (site of cellular respiration), Golgi apparatus (involved in protein modification and sorting), rough endoplasmic reticulum (involved in protein synthesis), and chloroplast (site of photosynthesis).
Conclude that the chloroplast is the organelle responsible for photosynthesis in plant and algal cells.
