1. Section 2 Review: Seedless Plants
Chapter 3 Page 79

2. Question Answer:
Compare and contrast the characteristics of mosses and ferns.
Alike: Reproduce by spores
Different: Unlike mosses, ferns have vascular tissue

3. Question Answer
Explain what fossil records tell about seedless plants that lived on Earth long ago.
Seedless plants dominated Earth long ago and grew much larger than they grow today.

4. Question Answer
Identify growing conditions in which you would expect to find pioneer plants such as mosses and liverworts.
In disturbed or new environments.

5. Question 4 Summarize the functions of vascular tissues.
The vascular system carries water, minerals, and food to plant cells. This allows the plant to grow bigger and thicker. The cells of vascular tissue also provide support.

6. Question Answer
Think Critically: The electricity that you use every day might be produced by burning coal. What is the connection between electricity production and seedless vascular plants?
Seedless plants (both vascular and nonvascular) formed ancient forests that decayed and became the coal we burn today as fuel.

7. Question Answer
Use Fractions: Approximately 8,000 species of liverworts and 9,000 species of mosses exist today. Estimate what fraction of these seedless nonvascular plants are mosses.
