• The town of Pleasantville experienced a very hot, dry summer with very little wind. How can these conditions affect the reproduction of seed plants?

• A. Pollen travels on wind and water, so the conditions could affect the ability of pollen to travel.

• B. Pollen requires hot temperatures and dry conditions, so the conditions could help many plants thrive.

• C. The conditions are external stimuli that could trigger a change in behavior in plants; they might wilt or die.

• D. Seed plants need water for sperm to swim, so the dry conditions could make it harder for the sperm of seed plants to fertilize eggs.
