Al-Huda Science Academy is focusing not only on short questions and long questions but also on Biology Chapter 11 MCQs Class 11. Entry Tests required a lot of effort on Multiple Choice Questions that should be of conceptual in nature. The users can participate without login to MCQs test. All MCQs are taken from the past papers of Punjab Boards. Chapter 11 of F.Sc Part 1 Biology is based on Bioenergetics.

Biology Chapter 11 includes

  • Conversion of solar energy into chemical energy
  • Chloroplasts – The sites of photosynthesis in plants
  • Photosynthetic pigments
  • Light – the driving energy
  • Role of carbon dioxide – A photosynthetic reactant
  • Reactions of photosynthesis
  • Respiration
