A waxy cuticle helps land plants...
conserve water
take up carbon dioxide
reproduce
stand upright
moisten the surface
Which structure attach mosses to soil?
Rhizoids
Rhizomes
Fibrous roots
Strobili
Taproots
Club mosses, horsetails, and ferns are_____plants.
multi-celled aquatic
nonvascular seed
seed-bearing vascular
seedless vascular
single-celled terrestrial
Suppose an efficient conducting system evolved in a moss that could transport water and other materials as high as a tall tree. Which of the following statements about “trees” of such a species would be true?
Spore dispersal distances would probably decrease.
Females could produce only one archegonium.
Unless its body parts were strengthened, such a “tree”
would probably flop over.
Individuals would probably compete less effectively for
access to light.
Nothing changes the efficiency because moss has evolved its own unique vascular pathway
Which of the following terms is NOT associated with a male
portion of a plant?
Megaspore
Antheridium
Pollen grains
Microspore
Tube cell
In a flower after fertilization, which the following tissues that are diploid?
carpel, integuments, and megaspore mother cell
carpel, integuments, and megaspore
carpel, megaspore, and zygote
carpel, megaspore mother cell, and endosperm
carpel, embryo sac, and microphyll
Reproduction in angiosperms can occur more quickly than in gymnosperms because
gymnosperm sperm requires water to swim to the egg
flowers always increase the rate of reproduction
angiosperm pollen tubes grow more quickly than
gymnosperm pollen tubes
angiosperms have nectaries
gymnosperm have more complex mechanism of seed dispersal
Which of the following characteristics is unique to all animals?
Sexual reproduction
Multicellularity
Lack of cell walls
Heterotrophy
Internal digestion
The distinction between sponges and other animal phyla is
based mainly on the absence versus the presence of
a body cavity
a complete digestive tract
mesoderm
tissues
locomotion appendages
The water vascular system of echinoderms...
functions as a circulatory system that distributes nutrients
to body cells
functions in locomotion and feeding
is bilateral in organization, even though the adult animal is
not bilaterally symmetrical
moves water through the animal’s body during filter
feeding.
acts as hydraulic pressurized skeleton to support the body
Which of the following is most closely related to lobsters?
Bivalves
Centipedes
Earthworms
Nematodes
Squids
Nematodes once were thought to be closely related to rotifers due to the presence of a pseudocoelom, but are now considered closer to the arthropods due to
molting
jointed appendages
wings
a coelom
segmented body
All of the following are characteristics of reptiles, except
cutaneous respiration
an amniotic egg
thoracic breathing
dry, watertight skin
four limbs
The fact that monotremes lay eggs...
indicates that they are more closely related to some reptiles
than they are to some mammals.
is a plesiomorphic (ancient) trait
demonstrates that the amniotic egg evolved multiple times.
is a result of ectothermy.
is a mechanism to overcome cold environment
Which of the following could be considered the most recent
common ancestor of living tetrapods?
a sturdy-finned, shallow-water lobe-fin whose appendages
had skeletal supports similar to those of terrestrial vertebrates
an armored, jawed placoderm with two pairs of appendages
an early ray-finned fish that developed bony skeletal supports
in its paired fins
a salamander that had legs supported by a bony skeleton
but moved with the side-to-side bending typical of fishes
a group of cartilaginous fishes that develop bony skeleton in their body and fins to be able walking on the land
