Chloroplasts are green because they contain the pigment chlorophyll, which is essential for photosynthesis. Chlorophyll absorbs light energy from the sun, primarily in the blue and red wavelengths, and reflects green light. This reflected green light is what we see, giving plants their characteristic green color.
Chloroplasts are found in plant cells and are responsible for converting light energy into chemical energy through photosynthesis. This process allows plants to produce their own food, making them essential for life on Earth.
