Chloroplasts are essential organelles in plants and algae, responsible for photosynthesis. They contain chlorophyll, facilitating the conversion of light energy into chemical energy, producing ATP and NADPH. These molecules are used in the Calvin cycle to create glucose and release oxygen. Chloroplasts also participate in other biosynthetic pathways and defense mechanisms. Their behavior, evolution, and the research history highlight their significance in plant biology and global ecological processes.
