Practice questions testing deep understanding of xylem, phloem, osmosis, and transpiration.
Q1. A gardener accidentally added too much chemical fertilizer to a potted plant. By the next day, the plant had severely wilted. Explain the biological phenomenon that caused this wilting based on your understanding of water transport.
Q2. If you deeply cut the bark (which contains the phloem) all the way around the trunk of a tree in a complete ring (a process called girdling), the tree will eventually die. Why does the tree die, and which part of the tree dies first?
Q3. Assertion (A): Transpiration creates a "suction pull" that helps water rise to the top of tall trees. Reason (R): As water evaporates from the leaves during transpiration, a vacuum is created that pulls more water up from the roots through the xylem.
