The organelle responsible for photosynthesis is called the chloroplast. Chloroplasts are found in the cells of green plants and some algae. These organelles contain chlorophyll, a green pigment that captures light energy from the sun.
During photosynthesis, chloroplasts convert carbon dioxide and water into glucose and oxygen using this light energy. The process is essential for the survival of plants and provides energy and oxygen for many other organisms, including humans, making chloroplasts crucial for life on Earth.
