A gardener planted large, healthy flower bulbs in her garden. When spring arrived, green shoots emerged from the bulbs, and some of them, but not all, produced flowers. She decided to dig up a few bulbs that flowered and a few that didn't to see if she
could see what the difference was. She was stunned to find that none of the bulbs looked healthy; they all appeared much smaller. What had happened?
A) The bulbs were a sugar source; sugars from them traveled up the phloem to the aboveground sugar sink.
B) The bulbs gave off water as they produced shoots; their smaller size was due to dehydration.
C) All of the molecules in the bulb were transferred to the aboveground shoots.
D) The bulbs were a sugar sink, so water flowed into them and out the roots, washing material from the bulb into the soil.
