A botanist wants to see how different colored light waves influence the growth of pea
plants. She puts the same number of seeds into three identical pots with the same kind
and amount of soil. She then gives them the same amount of water every three days for
the length of the experiment. One pot is placed into a dark windowless closet. Another
pot is left on the windowsill, and the third is placed under a lamp with a green bulb. She records the height of each plant every day for three months.
1. It is mentioned that the researcher used three identical pots. Describe two features of
the pots which will ensure their identicality.
2. Draw a diagrammatic illustration of the botanist’ experimental setup making sure that
the experimental and the control groups are clearly shown.
3. Write the procedure in the passive voice (reporting fashion) ​
