Understand that photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy stored in glucose.
Identify the organelle responsible for photosynthesis. In eukaryotic cells, this process occurs in the chloroplasts.
Recall that chloroplasts contain chlorophyll, the green pigment that captures light energy necessary for photosynthesis.
Differentiate between the roles of other organelles: the nucleus contains genetic material, ribosomes are involved in protein synthesis, and mitochondria are responsible for cellular respiration.
Conclude that the chloroplast is the organelle necessary for photosynthesis, as it is specifically adapted to capture and convert light energy into chemical energy.
