4. Which specialized plant structure attracts butterflies to transfer pollen?

• Bright flowers
• Hard shells on nuts
• Flower nectar
• Odors emitted by flowers

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.

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.

11. What is the role of hard shells on nuts in the probability of plant reproduction?

• They attract pollinators to transfer seeds
• They provide a protective covering during seed dispersal
• They assist in the absorption of sunlight for photosynthesis
• They help in the removal of excess water from the plant
