 The students will be learning about the various mechanisms such as channel or transport
proteins involved in nutrient uptake in plants.
 During the course students will gain knowledge about various components of
photosynthesis such as pigments, carotenoids, photosystems, oxygen evolving complex,
and electron carriers. Additionally, the fixation of photo-assimilatory products in the dark
phase of photosynthesis.
