carry nutrition to and remove wastes from the embryo during development.
The major difference between marsupials and placental mammals is
their pattern of embryonic development.
Unlike the young of reptiles, mammalian young depend on parental care for
food, learning, and protection. (All of the above)

Africa.
Of the following, the earliest member of the genus Homo was

B. spinach
Vegetables that we can eat come from various plant parts including
stems, roots, and leaves. (All of the above)
Fruits of cereal plants are called
grains.
Plant ecology is the study of the interaction between plants and
the environment.
A farmer alternately grows corn and a legume crop in a single field. The farmer's reason for doing this is probably
to allow the legumes to restore nitrogen to the soil that is depleted by the corn.
An example of a plant and an animal that have evolved together is
a plant flower that resembles the female of an insect species.
Mycorrhizae are
symbiotic associations between the roots of a plant and a fungus.
A beneficial relationship between a plant and a bacterium occurs when certain bacteria inhabit the roots of a plant and ____ that the plant can use.
fix nitrogen.
People have damaged natural plant populations by introducing
foreign plant species that become noxious weeds, diseases that kill native plants, and animals that consume native plants. (All of the above)
Which of the following plant products can be harmful if eaten?
B. holly berries
Approximately when did the cultivation of plants begin?
11,000 years ago.
The ancestors of today's land plants were probably
green algae.
The challenges faced by early land plants included
conserving water, reproducing on land, and absorbing minerals from the rocky surface. (All of the above)
The waxy protective covering of a land plant is called a
cuticle.
The cuticle
helps reduce the evaporation of fluids from a plant.
Some land plants developed an internal system of interconnected tubes and vessels called
vascular tissues.
The xylem in a plant
transports water and minerals to the stems and leaves.
The diploid form in a plant's life cycle is called the
sporophyte.
The haploid form in a plant's life cycle is called the
gametophyte.
Alternation between a haploid stage and a diploid stage in a plant's life cycle is called
alternation of generations.
In plants, haploid gametes are produced as a result of
mitosis.
The dominant generation in vascular plants is the
sporophyte.
Which of the following is not a nonvascular plant?
C. fern
Which of the following is not a characteristic of nonvascular plants?
C. They produce seeds
Which of the following is a reason why mosses are good pioneer plants?
A. They can create a layer of soil on bare rock
The water-retaining ability of peat moss makes it ideal for
use in garden-soil mixes, use in packing bulbs and flowers for shipping, and use in houseplant soils. (All of the above)
All of the following developed in some vascular plants and are not present in any nonvascular plants except
B. chlorophyll
The primary distinguishing characteristics of all vascular plants are
xylem and phloem; true roots, stems, and leaves.
Which of following is not a seed plant?
C. a fern
Which of the following is a characteristic of all seed plants?
A. a seed containing an embryo, a nutrient supply, and a protective coat
Pines, spruces, and firs are
gymnosperms.
The tallest trees in the world are species of
conifers.
Which of the following were the first land plants to evolve seeds?
B. gymnosperms
Seed plants are the dominant land plants because
the seeds they produce enable the plant to survive in a dormant state when conditions are not suitable for growth.
Monocots have
leaves with parallel veins.
Flowering plants are classified as monocots or dicots according to their number of
cotyledons.
The conducting cells of phloem are called
sieve tube members.
In xylem tissue, water moves from tracheid to tracheid through
pits.
The outermost layer consisting of ground tissue in a stem is the
cortex.
regions of active cell division in plants are called
meristems.
Meristems can be found
at the tips of stems and roots.
The lengthening of plant roots and shoots is called
primary growth.
During periods of primary growth at apical meristems, stems and roots
become longer.
The primary function of root hairs is
to absorb water and minerals.
The ground tissue in the center of roots and stems
provides support.
Secondary xylem and phloem are produced from the
vascular cambium.
