One of the reasons that so many farmers spray pesticides on
their crops is to decrease the amount of energy the crops need
to invest in the production of hairs on leaves to deter insect
herbivores. - ANSWER-false
You would like to cut down a tree in your backyard, but you
have no ax or chainsaw. Instead, you cut around the trunk of
the tree with a pocketknife and peel off the "bark" in a three-
inch thick strip. You are confident that this action will kill the
tree. Are you correct? - ANSWER-B) Yes, because the phloem
has been disrupted and sugar transport will no longer occur.
You may have heard that monarch butterflies (and their
caterpillars) are "poisonous" to many predators. What makes
these insects so toxic? - ANSWER-Monarch caterpillars store
cardenolides from milkweeds
Recall that the phloem sap of vascular plants moves through
the phloem as a result of mass flow. How are nutrients
transported through fungi? - ANSWER-(1) saprobes decompose
dead organic matter;

(2) parasites feed on living hosts
(3) mutualists live in symbiotic unions with other living
organisms. Saprophytic fungi
All bryophytes are relatively small. Which of the following is
thought to be one of the main limitations responsible for this
feature? - ANSWER-The male gametes of these land plants are
distributed through the water.
Which of the following statements is true regarding the fruits
produced by angiosperms? Select all correct choices. -
ANSWER-Fruits ripen in response to ethylene and fruits are
typically derived from the wall of the ovary
The ability to develop two types of sporangia was: - ANSWER-
Which of the following correctly describes the "fern" we see
when walking in the woods? - ANSWER-diploid sporophyte
What is the primary reason that fungi are important in the
carbon cycle? - ANSWER-fungi are able to reach incredibly large
sizes. their high ratio of surface area to volume allows them to
,3|Page
decompose large amounts of dead/decaying material, thereby
returning carbon to the atmosphere
One major innovation in the evolution of land plants was the
ability of the sporophyte to branch. This may have provided an
immediate advantage because: - ANSWER-
What would happen to a resulting seed of an angiosperm ovule
was fertilized by a pollen grain that had only one sperm? -
ANSWER-Nothing. The ovule would not be fertilized and the
endosperm would not develop and thus the embryo would not
have the resources it needs to develop.
A researcher is looking at different petri dishes containing the
yeast C. albicans. In the first dish she evaluates, she notices that
the yeast do not form hyphae. Is this a mutant strain of yeast? -
ANSWER-No, as yeast do not normally form hyphae.
Which of these plants are gymnosperms? - ANSWER-oak trees,
birches, maples
Hornworts are the most widely distributed bryophytes and are
the most diverse with the largest number of species. - ANSWER-
false

Which of the four major groups of gymnosperms is represented
today by a single species? - ANSWER-ginkos
Many antibiotics work by inhibiting the synthesis of
peptidoglycan, a component of the bacterial cell wall. What is a
possible mechanism of action for anti-fungal drugs? - ANSWER-
The sperm cells of bryophytes are dispersed by the wind. -
ANSWER-true
Dispersal an important part of reproduction. Which of the
following statements about dispersal is false? - ANSWER-
Dispersal occurs only on an evolutionary time scale (slowly; long
time)..
Which of the following is true about angiosperms? - ANSWER-
They have a triploid endosperm within the seed and an ovary
that becomes a fruit.
The only evolutionary process that leads to adaptive change is: -
ANSWER-natural selection
