Identify the process in question: photosynthesis, which is the conversion of light energy into chemical energy in plants and algae.
Recall that photosynthesis occurs in a specific organelle that contains pigments like chlorophyll to capture light energy.
Review the functions of the given organelles: Golgi apparatus (modifies and packages proteins), Mitochondrion (produces ATP through cellular respiration), Rough endoplasmic reticulum (synthesizes proteins).
Recognize that the organelle responsible for photosynthesis is the chloroplast, which contains thylakoid membranes where light-dependent reactions occur.
Conclude that the chloroplast is the organelle that carries out photosynthesis in plant and algal cells.
