Answer Key with Explanations
1. C – Nonvascular plants lack vascular tissues like xylem and phloem.
2. C – Bryophytes (mosses, liverworts, hornworts) are nonvascular plants.
3. C – Mosses are the most well-known nonvascular plants.
4. C – They rely on diffusion and osmosis for internal transport.
5. D – Moist environments are essential due to lack of water-conducting tissues.
6. D – In nonvascular plants, the gametophyte is dominant.
7. C – They reproduce via spores, not seeds or flowers.
8. B – Water is essential for sperm movement; reproduction is via spores.
9. D – Their size is limited due to the absence of vascular support.
10. C – Rhizoids anchor the plant but don't absorb water like true roots.
11. D – Algae are not considered true nonvascular plants.
12. D – Sperm swim through water to reach the egg.
