Some plant species are not able to acclimate when transferred from a sunny to a shady environment, or vice versa, lack of acclimation indicates that these plants are specialized for either a sunny or a shady environment. When plants adapted to deep-shade conditions are transferred into full sunlight may leaves experiences;

Some differences is found between plants that normally grow in full sunlight and those that grow in the shade given below;

  COLUMN A                                                              COLUMN B

    

  A- SHADED PLANTS                          i-  Light compensation points range from 10 to 20 μmol m–2 s–1

  B- SUN PLANTS                                 ii-  low light Compensation point and have lower maximum photosynthetic rates

                                                               iii-  Light compensation points range from 1 to 5 μmol m–2 s–1

                                                               iv-  the respiration rates in plants are very low

                                                                v-  Plants CO2 assimilation take place very late
