Final answer:
The energy-absorbing molecules of plant cells are located in the thylakoids of the chloroplasts.
Step-by-step explanation:
The energy-absorbing molecules of plant cells are located in the chloroplasts. Chloroplasts are the organelles in plant cells responsible for photosynthesis, the process by which plants convert light energy into chemical energy.
Within the chloroplasts, the energy-absorbing molecules are found in the thylakoids. Thylakoids are flattened membrane sacs that contain chlorophyll, the pigment that captures light energy.
Therefore, the correct answer is thylakoids.
