Scientists classify plants into two major groups based on the internal structures of the stems. What are these two groups called?

• water plants and land plants
• vascular and non-vascular
• gymnosperms and angiosperms
• seedless and seed plants 

What is the name of the process outlined in part E of the diagram above?

• photosynthesis
• transpiration
• cellular respiration
• chlorophyll

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

• Pollen requires hot temperatures and dry conditions, so the conditions could help many plants thrive
• Pollen travels on wind and water, so the conditions could affect the ability of pollen to travel
• 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.
• There won't be an effect in reproduction

As you walk past a field of sunflowers, you notice the flowers are all facing the same directions. This is an example of what?

How does a virus use a host to reproduce?

• The virus only uses the host cell for shelter; it does not use a host cell to reproduce
• The host cell provides the virus with resources and shelter; its proteins replicate the genetic material of the virus
• The host cell only provides the virus with the food it needs to reproduce on its own
• The virus uses the host cell to provide a way to reproduce only

Where would you expect to see a plant that does not have a vascular system?

• Deeply rooted in a forest with a trunk that reaches 20 meters or more
