36 bean plants were grown in potting soil. The same amount of soil was used in each pot and it had no
added nutrients. The plants were grown under 24 hour light, for the same length of time. They were
watered everyday with 22.18 milliliters of water. The amount of sugar in the water was either: no sugar,
(control), 25 grams of sugar per liter of water, 50 grams of sugar per liter of water or 75 grams of sugar
per liter of water. The plants grew for 28 days. Each plant was removed gently from the pot, rinsed in
water, and measured. The roots and the plant itself were measured separately.
