75. ANS:
No. Liverworts and hornworts are nonvascular plants, which means they do not have a vascular
system to transport water through their bodies. All parts of these plants must obtain water directly
from their surroundings. A wet or moist environment makes obtaining water an easier task.
PTS: 1

OBJ: CaLS.10.2.1 Name some nonvascular plants and list the characteristics they share.

76. ANS:
The underside of the frond would have many spore cases. The upper surface would not have spore
cases.

OBJ: CaLS.10.2.2 Name some seedless vascular plants and lists the characteristics they share.
STA: S 7.5.a
BLM: application
77. ANS:
Yes, you could tell the difference. Xylem carries water and nutrients up from the roots to the stems
and leaves. Phloem carries food down from the leaves to the stems, roots, and other parts of the
plant.

OBJ: CaLS.10.3.1 Identify the characteristics that seed plants share.
STA: S 7.5.a
BLM: application
78. ANS:
Most seeds begin to germinate when they absorb water from the environment. Keeping the seeds
in a dry place will prevent them from germinating before it is time for them to be planted.

DIF: L2
OBJ: CaLS.10.3.2 Explain how seeds become new plants.
STA: S 7.5.a
BLM: application
79. ANS:
The presence of leaves with branching veins and five-petaled flowers indicates that the plant is a
dicot. Therefore, you would expect to find the stem’s vascular tissue bundles arranged in a circle,
as occurs in dicots.

OBJ: CaLS.10.5.4 Describe the two types of angiosperms.
STA: S 7.5.f
BLM: application
80. ANS:
Plants go through two stages during their life cycle. The first stage is the sporophyte. During this
stage, the plant produces spores, which grow into gametophytes. Gametophytes then grow into
structures that produce gametes, or sex cells. Eggs are fertilized by sperm and grow into new
sporophytes. The cycle then begins again.
