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

Match the correct combination of column A with the column B;
