Accepted Answer

A)   lycophytes
B)   gymnosperms
C)   bryophytes
D)   ferns
E)   No plants can reproduce except during rainy weather. Because gymnosperms do not have flagellated sperm which require a watery film for swimming, they can reproduce even in moderately dry conditions.F) B) and C)
G) A) and E)

Question 6

Which statement about chytrids is incorrect?

Accepted Answer

A)   They have flagellated spores and gametes.
B)   They are obligate parasites.
C)   Some are unicellular, while others form hyphae.
D)   Some have an alternation-of-generations life cycle.
E)   Some stages of their life cycle are motile. Most chytrids live freely in the soil and water, not as parasites.F) A) and E)
G) D) and E)

Question 7

What would you predict as a likely consequence of eradicating all fungi from soil before sowing it with plant seeds?

Accepted Answer

A)   Although the plants might grow, they would be unlikely to thrive due to the lack of mycorrhizal fungi.
B)   The plants would grow much more vigorously because they would not have to compete with fungi for nutrients.
C)   The plants would grow much more vigorously because they would not need to fight off fungal diseases.
D)   No plants would be able to grow because mycorrhizal fungi are essential for the germination of seeds.
E)   The plants would grow as normal because the presence or absence of fungi has no impact on plants. Mycorrhizal fungi exist in mutualistic relationships with most plants, enhancing their growth.F) C) and D)
G) None of the above

Question 8

By definition, a fruit is derived from the

Accepted Answer

A)   archegonium.
B)   corolla.
C)   calyx.
D)   ovary.
E)   stamen. Fruits are ovary-derived structures that enclose the seeds of angiosperms.F) A) and B)
G) A) and E)

Question 9

Which structures were required for the evolution of the ferns and gymnosperms?

Accepted Answer

A)   seeds and flowers
B)   megaphylls and seeds
C)   microphylls and megaphylls
D)   flowers and vascular tissue
E)   megaphylls and vascular tissueF) B) and D)
G) A) and E)

Question 10

If you are studying a eukaryotic, multicellular, non-photosynthetic organism, what piece of information would be least useful in determining if it is a fungus or an animal?

Accepted Answer

A)   It is motile.
B)   It has cell walls.
C)   It ingests or absorbs its food.
D)   It has specialized tissues and organs.
E)   All of the choices would be equally useful. Although most fungi are nonmotile, chytrids do have motile stages in their life cycle. Therefore, motility would be the least useful characteristic for evaluation.F) C) and E)
G) A) and C)

Question 11

Which of the following groups provides protection and nourishment to the embryo?

Accepted Answer

A)   all plants
B)   angiosperms only
C)   gymnosperms only
D)   bryophytes only
E)   lycophytes only All plants protect and nourish their embryos to some degree.F) A) and C)
G) A) and E)

Question 12

In a fungal life cycle, which of the following is/are diploid?

Accepted Answer

A)   the zygote only
B)   the spores only
C)   the hyphae only
D)   the hyphae and spores but not the zygote
E)   the zygote, spores, and hyphae The zygote is the only diploid part of the fungal life cycle; the rest is haploid.F) C) and D)
G) B) and C)

Question 13

________ is the vascular tissue that conducts water and minerals from a plant's roots to its leaves.

Accepted Answer

A)   Endosperm
B)   Phloem
C)   Hypha
D)   Xylem
E)   CorollaF) C) and E)

Accepted Answer

A)   protection of the embryo
B)   evolution of vascular tissue
C)   evolution of microphylls
D)   evolution of seeds
E)   evolution of flowers in order to attract pollinators It is believed that the evolution of protection for the embryo was the first step required for the evolution of land-based plants. Without an embryo that could survive on land, the rest of the features would have been useless.F) A) and E)
G) B) and C)

Question 16

While walking in the woods, you come across some low-growing plants clustered at the base of a tree. You collect one as a specimen for biology class. Upon examination in the lab, you find that the leaf-, stem-, and root-like structures contain no vascular tissue. The plant is
