Choose all correct answers: Which of the following are challenges a plant need to overcome to reproduce...

• Plants cannot move, yet need to get their pollen to an egg to fertilize it.

• Plants cannot move, yet need to get their offspring away from them so they do not compete for resources.

• Plants need to get enough water, carbon dioxide, light, and minerals to both grow and produce flowers.

• Plants in colder climates need to find a way for their offspring or seeds to survive the winter months.

• Plants can move and so they can find other plants to reproduce with and pollinate each other.

Some plants and animals have been known to reproduce both sexually and asexually. What is an advantage of asexual reproduction?

• In asexual reproduction, the species can continue even if no mate can be found.

• Asexually produced organisms have more variation.

• Asexually produced organisms are more likely to escape predators.

• Asexually produced organisms have less variation and are more likely to die off if the environment changes suddenly.

Your teacher makes the claim that many plant structures have evolved to take advantage of animal behaviors to reproduce. Cite two pieces of evidence from the plant structures worksheet. For each piece of evidence, state the example number from the plant worksheet and explain how the plant structure causes the animal behavior.

Your teacher makes the claim that animals who protect their young do not need to produce as many eggs. Cite two pieces of evidence from the Animal Behavior worksheet.

For each piece of evidence, state the example number from the animal worksheet and explain how the animal behavior affects the number of eggs needed for some offspring to survive.
