Learning in which an animal acquires a behavior through practice in order to receive a reward or avoid punishment is called
operant conditioning.
habituation.
classical conditioning.
innate conditioning.
During migration, animals undertake a
seasonal movement.
repeating daily cycle of behavior.
sleeplike state.
search for new permanent habitats.
The members of a society
belong to at least two species.
belong to the same species and interact closely with each other.
act independently for each individual’s benefit.
are usually unrelated to one another.
It is advantageous for grazing mammals to gather in groups because groups
can make the available food resources last longer.
can migrate more easily than individuals can.
are more difficult for predators to locate than individuals are.
offer greater protection from predation.
Certain behaviors are innate in animals because they are essential for
survival immediately after birth
guarding territory.
acquiring other behaviors.
developing a circadian rhythm.
The type of learning that occurs when a stimulus produces a particular response because it is associated with a positive or negative experience is
classical conditioning.
operant conditioning.
habituation.
trial-and-error learning.
What type of social behavior are grizzly bears exhibiting when they leave their scent on trees?
imprinting
operant conditioning
aggression
territoriality
The survival of plants depends on
sunlight, water, and organic nutrients.
water, minerals, and organic nutrients.
water, minerals, and sunlight.
water, oxygen, and sunlight.
Within bryophytes, the eggs are produced in
archegonia
tracheids
antheridia
sporangia
A structure essential to the reproduction of gymnosperms is the
flower
spore
cone
angiosperm
The transfer of pollen from the male reproductive structure to the female reproductive structure is called
ovulation
implantation
pollination
photosynthesis
The seed leaves of a plant are known as
dicots
cotyledons
monocots
clades
Herbaceous plants are angiosperms that
have stems that are smooth and nonwoody.
have stems made of cells with thick cell walls.
include trees, shrubs, and vines.
include grasses, roses, and tomatoes.
Which of the following is NOT a characteristic of dicots?
branched veins
taproot
parallel veins
two cotyledon
Plants cultivated for food are mostly
gymnosperms
woody plants
angiosperms
bryophytes
What is a basic difference between a sporophyte and a gametophyte?
A sporophyte is a reproductive structure while a gametophyte is not.
A sporophyte undergoes sexual reproduction while a gametophyte undergoes asexual reproduction.
A sporophyte is part of the diploid phase while a gametophyte is part of the haploid phase of the plant life cycle.
A sporophyte is much smaller than the gametophyte.
Xylem tissue is important because it
can conduct water over long distances.
allows water to diffuse from the roots.
carries carbohydrates to all parts of the plant.
carries out photosynthesis.
In angiosperms, xylem consists of tracheids and
sieve tube elements.
companion cells.
vessel elements.
parenchyma.
Vascular tissue in plants consists of
meristems.
xylem and phloem.
parenchyma and collenchyma.
epidermis.
The vascular cylinder of a root consists of
xylem only.
phloem only.
phloem and xylem.
phloem, xylem, and ground tissue.
During primary growth, a stem
increases in length.
produces flowers.
increases in width.
produces wood.
Oxygen and carbon dioxide move in and out of a leaf through the
palisade mesophyll.
guard cells.
phloem.
stomata.
Ground tissue is found in a plant’s
stems only.
stems and leaves only.
roots and stems only.
roots, stems, and leaves.
If some of the xylem of a young oak tree were destroyed, it would most likely interfere with the tree’s ability to
conduct sugars to the roots.
absorb sunlight.
absorb nutrients from the soil.
conduct water to the leaves.
The outer covering of a plant consists of
ground tissue.
vascular tissue.
dermal tissue.
meristematic tissue.
One of the three main functions of stems is to
carry out photosynthesis.
carry water and nutrients between roots and leaves.
store carbohydrates.
store water.
Most of the photosynthesis in plants takes place in the
mesophyll.
guard cells.
stomata.
xylem.
Which of the following is NOT part of the female structure of a flower?
filament
style
stigma
ovary
Vegetative reproduction can be a disadvantage when
conditions in the physical environment suddenly change.
conditions are favorable for growth.
the parent plant is not competing with other organisms for resources.
the parent plant must reproduce quickly.
What is the source of ethylene gas in a plant?
leaf buds
root hairs
fruit tissues
lateral meristems
The growth of plant seedlings is usually
phototropic and gravitropic.
thigmotropic and gravitropic.
phototropic and influenced by ethylene.
gravitropic and influenced by ethylene.
When a plant responds to changes in the relative lengths of light and darkness, the plant is responding to
gravity
touch
pigments
photoperiod
Cytokinins are plant hormones responsible for
dropping organs no longer needed by the plant.
inhibiting cell division and halting growth.
stimulating cell division and growth of new organs in injured plants.
stimulating cell elongation.
Which of the following BEST describes how people rely on plants?
People get food, raw materials, and medicines from plants.
People use plants only for food.
Plants break down decomposing organisms and wastes.
All medicines come from plants.
Which of the following crops is NOT a major food supply for humans?
rice
soybean
corn
tomato
Gravitropism and phototropism are controlled by
photosynthesis
hormones
touch
photoperiod
The seeds of angiosperms develop within
anthers
cotyledons
shells
fruits
Seeds dispersed by wind or water are typically
contained in lightweight or buoyant fruits that float on air or water.
enclosed in fleshy, nutritious fruits.
enclosed in hard shells.
attached to burrs or hooks.
A typical flower contains a male structure called a
carpel
petal
stamen
