- Class periods are assumed to be 60 minutes long.
See the following Web sites for appropriate laboratory activities:
1. Students can investigate plant structures and plant diversity by doing the lab What Parts of a Plant Do We Eat? (Lesson 15.1).
2. In this simple investigation, students will collect and analyze pollen released by wind-pollinated plants. (Lesson 15.2)
These Web sites may also be helpful:
1. This Web site has a wide range of information on plants, including the fossil record, life history, ecology, systematics, and morphology of plants.
2. At these URLs, you can find more information about bryophytes.
3. Students can interact with a virtual plant cell at this Web site.
4. For detailed coverage of all lesson topics, visit this URL.
5. The existence of non-photosynthetic plants is often overlooked. Direct students to the URL below. It focuses on the parasitic plant Rafflesia arnoldii, which also produces the world’s largest flower.
6. Go to this USDA Web site for detailed data and images of a huge number of plants.
