Question

Roots, stems, leaves, and flowers all play integral roles in the life of a plant. Think about what you learned in this unit and decide which of these parts is most important to plants and, therefore, to the survival of life on Earth. Defend your answer

Answer 1

Do you recall anything you've learned in your unit about plants?

Answer 2

Hi, and welcome to QuestionCove!

Like the question says, all of the structures listed are important to plants in general. Roots support plants in the ground and allow absorption of moisture and nutrients; stems give the plant structure and upward growth; leaves perform photosynthesis, so plants can produce the energy they need to grow and survive; flowers are an important structure in plant reproduction, so plants can make more plants

I don't think there is a single right answer to the question of which part is most important, but the question does ask you to pick one. I think the important part is less about which part you choose and more about how you defend your answer.
So, like Sherixn suggested, think about what you've learned about plants and their structures. Go with your gut and write whatever you think is important about the plant part you decide to defend :)
