The light-absorbing antenna systems are organised in different manner, which of the following statements about antenna would be Incorrect?

#Unit 6. System Physiology – Plant
  1. The antenna systems of different classes of photosynthetic organisms are almost same , in contrast to the reaction centre, which appear to be similar in even distantly related organisms
  2. The variety of antenna complexes reflects evolutionary adaptation to the diverse environments in which different organisms live, as well as the need in some organisms to balance energy input to the two photosystems
  3. The size of the antenna system varies considerably in different organisms, ranging from a low of 20 to 30 bacteriochlorophylls per reaction centre to generally 200 to 300 chlorophylls per reaction centre
  4. The molecular structures of antenna pigments are associated in some way with the photosynthetic membrane, In almost all cases, the antenna pigments are associated with proteins to form pigment–protein complexes
