What is the green substance in plant chloroplasts called?

Explanation:
Plants rely on a pigment inside chloroplasts to capture light energy for photosynthesis. This green substance is chlorophyll, the main pigment that absorbs blue and red light and reflects green, which is why leaves look green. Chlorophyll sits in the thylakoid membranes of chloroplasts and is essential for driving the light-dependent reactions that power glucose production from carbon dioxide and water. Other terms aren’t pigments in chloroplasts: chloride is just an ion, chloroplast is the organelle itself, and chlorosis is a condition where leaves lose chlorophyll and turn yellow.
