Make them see how beautifully pigments are arranged by nature in the chloroplasts. What are the photosynthetic pigments present in my leaf? Predict the genotypes in the patient's family They need to use an element that has chemical behavior similar to that of silicon (Si) and lead (Pb). The homework involved in the students part overwhelms them as the process of photosynthesis where plant pigments are involved in an extensive one. Initially, add only a small amount of acetone to begin the grinding process. light energy and convert it into chemical bond energy that is then useable by the plant; this. Large energy gap High energy UV light small energy gap pigments, can absorb visible light. Most plants are green, so they reflect this color and absorb other wavelengths, which they use for photosynthesis.
