  1. 1. Photosynthesis
  2. 2. Photosynthesis <ul><li>Light absorption takes place in the chloroplasts </li></ul><ul><ul><li>Double membrane bound </li></ul></ul><ul><ul><li>Stacks of thyakaloids are called grana and suspended in a fluid called stroma (CD) </li></ul></ul><ul><li>Three major pigments </li></ul><ul><ul><li>Chlorophyll A </li></ul></ul><ul><ul><li>Chlorophyll B </li></ul></ul><ul><ul><li>Carotenoid </li></ul></ul>
