Observation

It is observed that initially the plants in pots D and E grew faster than the plants in pots A, pot B and pot C. However by day 6 the plants in all the pots had grown to almost the same height. From days 7 onwards, it is observed that the plants in pots A, B and C were taller then the plants in pots D and E.

Use the  graph below to plot the results of above observations.
