Answer
This statement appears to be true. Considering the water loss data, plant 2 shows a lower water loss per unit area, indicating better adaptation to dry conditions.
Step 2
B. At 12:00 noon, plant 1 has a greater water loss per unit area than plant 2.

Answer
This statement is correct. The graph indicates that at noon, the water loss from plant 1 is indeed higher than from plant 2.
Step 3
C. At 10:00 am the average stomatal aperture will be greater in plant 1 than in plant 2.

Answer
This conclusion is plausible based on the observed water loss. A greater water loss at that time suggests that plant 1 likely has wider stomatal openings compared to plant 2.
Step 4
D. At 5:00 pm the rate of photosynthesis will be greater in plant 2 than in plant 1.

Answer
This statement is likely accurate. With a lower water loss in plant 2, it is reasonable to infer that it would maintain a higher rate of photosynthesis than plant 1 at that time.
