6. What is the main purpose of a flower?

• spread seeds
• protect the plant
• attract pollinators
• absorb water

8. Which explanation best describes why animals such as frogs and fish produce large numbers of offspring at one time?

• Frogs and fish are prettier than other animals so they need to have more offspring.
• Frogs and fish produce large numbers of offspring because they do not care for their young. The large number helps ensure some of the young survive to adulthood.
• Frogs and fish are able to provide care for large numbers of offspring at once.
• Frogs and fish select their favorite offspring to care for out of a large group.

9. Which of the following is an example of a plant structure that assists in the probability of successful reproduction?

• Brightly colored leaves for photosynthesis
• Thick bark for protection against external threats
• Efficient root system for nutrient absorption
• Spiky thorns to deter herbivores

10. Why do the seeds of some species, such as dandelions, fly easily in the wind?

• So the seeds can disperse over larger areas of land.
• So the seeds can fly right next to the parent plant.
• So the seeds can find a mate.
• So the seeds can fly into bird nests.
