The primary plant pigment found in chloroplasts is "chlorophyll." This pigment is crucial for the process of photosynthesis, where plants convert sunlight into chemical energy. Chlorophyll absorbs primarily blue and red light while reflecting green wavelengths, which is why plants appear green. It exists mainly in two forms: chlorophyll a and chlorophyll b, each playing distinct roles in capturing light energy for photosynthesis. Beyond its photosynthetic functions, chlorophyll's role in plant growth and health is significant, as it aids in energy production, growth regulation, and resilience against environmental stressors. It is foundational for sustaining life on Earth as it supports food webs.
