This section explains how vascular tissue is important to ferns and their
relatives. It also describes the characteristics of three phyla of spore-bearing
plants and describes the stages in the life cycle of ferns.
Evolution of Vascular Tissue
(page 560)
1. What is vascular tissue? It is a type of tissue that is specialized to conduct water and
nutrients.
2. What kind of cells did the first vascular plants have that were specialized to conduct
Tracheids
water?
3. Circle the letter of each sentence that is true about tracheids.
a. They are hollow cells.
b. They are connected end to end.
c. Their thick cell walls resist pressure.
d. They are the key cells of phloem.
4. Complete the table about vascular tissue.
VASCULAR TISSUE
Type of Tissue
Function
Xylem
Carries water upward from the roots to every part of a plant
Phloem
Transports nutrients and carbohydrates produced by photosynthesis
5. Is the following sentence true or false? Phloem and xylem cannot move water and
false
nutrients against the force of gravity.
(pages 561–562)
6. Complete the table about plant structures.
PLANT STRUCTURES
Structure
Description
Roots
Underground organs that exchange water and minerals with the environment
Leaves
Photosynthetic organs that contain one or more bundles of vascular tissue
Stems
Supporting structures that connect roots and leaves, carrying water and nutrients between them

7. Spore-bearing vascular plants include what three types of plants?
a. Club mosses
b. Horsetails
c. Ferns
8. Is the following sentence true or false? Vascular plants have true roots and stems.
true
9. The fossilized remains of ancient forests of club mosses exist today as huge beds of
coal
.
10. Why is Equisetum called “horsetail”? Its stems look similar to horses’ tails.
11. Circle the letter of each structure a horsetail has.
a. stems
b. cones
c. leaves
12. Ferns are members of phylum
d. roots
Pterophyta
.
13. What are rhizomes? They are the creeping, underground stems of ferns.
fronds
14. The large leaves of ferns are called
.
15. Fronds grow from what fern structures? They grow from rhizomes.
16. In what kind of habitats are ferns most abundant? They are found in wet, or at least
seasonally wet, habitats around the world.
Life Cycle of Ferns
(pages 562–563)
17. What is the dominant stage in the life cycle of ferns and other spore-bearing vascular
plants? The diploid sporophyte is the dominate stage.

18. Fern sporophytes produce haploid spores on the underside of their fronds in tiny
containers called
sporangia
.
19. What are sori? Sori are clusters of sporangia.
20. Are the spores of ferns haploid or diploid?

21. Label each drawing of a fern as either the sporophyte or the gametophyte.
Gametophyte
Sporophyte
22. Where are the antheridia and archegonia found in ferns? They are found on the
underside of the gametophyte.
23. Why does fertilization in ferns require at least a thin film of water? The water allows the
sperm to swim to the eggs.
24. Circle the letter of each sentence that is true about the life cycle of ferns.
a. The zygote grows into a new gametophyte.
b. The sporophyte is a heart-shaped, green structure.
c. Fern sporophytes often live several years.
d. When spores germinate, they grow into haploid gametophytes.
