ANSWERS
Which of the following statements about plant divisions is false? - Correct Answers -All
vascular plants produce seeds.
The land plants are probably descendants of which of these groups? - Correct Answers
-green algae
Alternation of generations means that plants produce: - Correct Answers -both haploid
and diploid multicellular organisms
Which of the following traits of land plants allows them to grow in height? - Correct
Answers -tracheids
Why did land plants lose some of the accessory pigments present in brown and red
algae? - Correct Answers -Sunlight is not filtered by water or other algae on land;
therefore, there is no need to collect light at additional wavelengths made available by
other pigment coloration
What is the difference between extant and extinct? - Correct Answers -Paleobotanists
distinguish between extinct species, which no longer live, and extant species, which are
still living.
What characteristic of Charales would enable them to survive a dry spell? - Correct
Answers -sporopollenin
Which one of these characteristics is present in land plants and not in Charales? -
Correct Answers -alternation of generations
o an alga, what is the main advantage of producing drought-resistant structures? -
Correct Answers -It allows for survival through periodic droughts and colonization of
environments where the supply of water fluctuates.
Which of the following statements about the moss life cycle is false? - Correct Answers -
The rhizoid buds to form a mature gametophyte
, Which of the following structures is not found in bryophytes? - Correct Answers -root
Stomata appear in which group of plants? - Correct Answers -hornworts
The chromosome complement in a moss protonema is - Correct Answers -1n
Why do mosses grow well in the Arctic tundra? - Correct Answers -They do not have
true roots and can grow on hard surfaces.
In areas where it rains often, mosses grow on roofs. How do mosses survive on roofs
without soil? - Correct Answers -Mosses absorb water and nutrients carried by the rain
and do not need soil because they do not derive much nutrition from the soil.
What are the three classes of bryophytes? - Correct Answers -The bryophytes are
divided into three phyla: the liverworts or Hepaticophyta, the hornworts or
Anthocerotophyta, and the mosses or true Bryophyta.
Which of the following statements about the fern life cycle is false? - Correct Answers -
Sporangia form on the underside of the gametophyte.
Microphylls are characteristic of which types of plants - Correct Answers -club mosses
A plant in the understory of a forest displays a segmented stem and slender leaves
arranged in a whorl. It is probably a ________. - Correct Answers -horsetail
The following structures are found on the underside of fern leaves and contain
sporangia: - Correct Answers -sori
The dominant organism in fern is the ________. - Correct Answers -sporophyte
What seedless plant is a renewable source of energy? - Correct Answers -sphagnum
moss
How do mosses contribute to returning nitrogen to the soil? - Correct Answers -Mosses
decompose rocks and release nitrogen.
How did the development of a vascular system contribute to the increase in size of
plants? - Correct Answers -Plants became able to transport water and nutrients and not
be limited by rates of diffusion. Vascularization allowed the development of leaves,
which increased efficiency of photosynthesis and provided more energy for plant
growth.
Which plant is considered the most advanced seedless vascular plant and why? -
Correct Answers -Ferns are considered the most advanced seedless vascular plants,
because they display characteristics commonly observed in seed plants—they form
large leaves and branching roots.
