Chloroplasts are cell organelles found in plant cells and other photosynthetic organisms. These structures are responsible for carrying out photosynthesis, the process by which plants convert sunlight, water, and carbon dioxide into energy-rich molecules like glucose. Chloroplasts contain chlorophyll, a green pigment that absorbs sunlight and plays a key role in capturing and converting light energy into chemical energy. In addition to photosynthesis, chloroplasts also play a role in plant development, growth, and stress response. Studying chloroplasts can provide insights into how plants adapt to changing environmental conditions and may have applications in agriculture, biotechnology, and environmental science.
