Worked Solution

Step 1: Compare the two systems. Both have tube-like structures for transport. Step 2: Both transport essential substances like water and nutrients. Step 3: The human circulatory system relies on the heart to pump blood, whereas plants transport substances without an active pumping organ.

Correct answer: The human system requires a pump (the heart), while the plant system does not.
