Final answer:
Chloroplasts are the plant cell organelles responsible for photosynthesis, containing chlorophyll to capture solar energy and produce glucose.
Step-by-step explanation:
The organelle inside of a plant cell that uses radiant energy to make sugar (glucose) from water and carbon dioxide through the process of photosynthesis is called a chloroplast. Chloroplasts are essential for photosynthesis, which is the process by which plants make their own food. These organelles are enclosed by an inner and outer phospholipid membrane and contain stacks of thylakoids, called grana, where the photosynthesis occurs. The pigment chlorophyll, which gives plants their green color, is also located within the thylakoids and plays a critical role in capturing solar energy.
