Answer:
Chloroplasts
Step-by-step explanation:
Chloroplasts are found in cells of leaves and green parts of the stem. They contain green pigment called chlorophyll which makes photosynthetic cells to appear green. They are sites of photosynthesis. Chlorophyll traps light energy from the sun. The energy is used to drive the manufacture of sugars from carbon dioxide and water, a process called photosynthesis.
