Many plants are excellent at photosynthesis because they
  1. have few mesophyll cells in their leaves
  2. are equipped with many leaves that have many mesophyll cells, which in turn have many chloroplasts
  3. are able to transform light energy into heat energy for cellular work
  4. can carry out photosynthesis in their roots, stems, flowers as well as their leaves
  5. produce an abundant supply of oxygen that is an important input for photosynthesis
College Botany

  3. chloroplasts, the primary electron center, and chlorophyll
  4. cristae, reaction center, and ATP synthase
  5. reaction center, inner membrane, and matrix
