Plant Structures (p. 69)


Step 1. Questions

Leaves can be as small as a freckle or as big as your head. But no matter what size, leaves perform the same important jobs.

Write a report about what happens as a plants grows new leaves. You will research how plants grow and why they grow leaves. Here are some questions to guide your research:
  • How does a plant start to grow? What part of a plant grows first?
  • When do leaves appear on a plant?
  • Why do some plants lose their leaves and grow new ones?
  • How are leaves alike and different?
  • What important function do leaves have?
Are you ready? Begin by visiting the Web sites listed in Step 2. Look for answers to the questions above, and write down what you learned in the note-taking boxes.

You may use search engines to research other Web sites. Or research plant life cycles at the library. When you are finished, follow Steps 3 and 4 to write your report.



Step 2. Research

Research answers for the questions you were asked in Step 1. Visit these Web sites. Take notes about them on this page, too!
