Answers
1
Which of the following define a plant?
autotrophic
sessile
multicellular
all are characteristics of plants
2
In what ways can a flower attract a pollinator? (More than 1 can be correct)
theft
bribery
monetary gifts
trickery
3
Which of the following is a new challenge plants faced in moving to land?
desiccation
predation
nutrient availability
light availability
4
What is an endosperm?
the male portion of a flowering plant
tissue that develops into a protective seed coat
leaves that are part of the embryo
a food-storing tissue of the seed
5
Which of the following is included as a male part of a flower :
pollen tube
anther
pistil
style
6
What do ferns and mosses have in common?
both lack roots and vascular tissue.
both require water for fertilization to occur.
both have roots and vascular tissue.
both release pollen via wind.
7
What challenges does being immobile bring to plants?
problems finding a mate.
problems obtaining food.
problems resisting predation.
all of these.
8
Double fertilization allowed for the evolution of what:
carpets and windows
flowers and fruits
pollen and ovules
flowers and pistils
9
What is the structure labeled F?
style
petal
anther
filament
10
What is the structure labeled C?
carpool
sepal
style
stigma
11
__are the specialized reproductive organs whose function is to bring together the sperm and egg
Flowers
Seed
Pollen
Leaves
12
Which two groups of plants produce spores?
bryophytes and pterophytes
bryophytes and gymnosperms
angiosperms and ferns
ferns and flowering plants
13
What is the function of an endosperm?
protects the developing plant embryo.
to give plants a form of communication.
stores waste products produced by the plant embryo
food-storage for the developing plant embryo
14
Which is an example of an angiosperm?
venomous tentacula
pine trees
liverworts
grasses
15
The common term for the action of transferring pollen grains from an anther onto a stigma is
intercourse
fertilization
reproduction
pollination
16
What is the difference between spores and seeds? (more than 1 can be correct)
seeds: single cells of plants made from venomous tentacula
seeds are multicellular embryos with nutrients
spores are multicellular w/ nutrients for the growing plant
spores are single cells with DNA, RNA, and some proteins
17
Which is an example of a gymnosperm?
all are examples of gymnosperms
conifers
cycads
gnteophytes
18
What plant group is most diverse?
flowering plants
ferns
gymnosperms
mosses
19
Which of the following lists the order of evolutionary events in plants from earliest to recent
roots; vascular tissue; pollen; flowers
vascular tissue; pollen; flowers; cuticle
spores; roots; cuticle; vascular tissue
cuticle; flowers; seeds; spores
20
What does meiosis produce?
germs
haploid cells
diploid cells
fruits
21
Which two plant groups, taken together, make up a monophyletic group?
gymnosperms and bryophytes
gymnosperms and ferns
flowering plants and ferns
flowering plants and gymnosperms
22
What process usually follows pollination in flowering plant reproduction?
fertilization
mitosis
meiosis
embryo development
23
Which is NOT a method of seed dispersal?
animals
water
wind
jogging
24
What is required for wind pollination to be successful?
release small amounts of pollen.
wet weather.
large, colorful flowers
relative proximity of individuals to each another.
25
As plants have evolved, what has happened to their gametes?
gametes are released by the wind
gametes reduce in size
gametes become nonexistent.
gametes get larger
26
What do ovaries become after fertilization?
shoots
fruits
cones
seed
27
What is the function of petals?
attract insects to collect and disperse fruit
serve to attract animals to collect and disperse pollen
present to protect seeds
present to protect the stamens and carpels
28
Why is having double fertilization an advantage in angiosperms?
to be able to form an endosperm
endosperm forms ONLY when egg is fertilized-not waste energy
to allow for angiosperms to become diverse
there is no advantage to this.
29
What does fertilization produce?
embryo
pollen
spores
gametes
30
What is the likely pollinator for a flower which stinks and does NOT produce nectar?
flies
bats
bees
birds
31
A plant that has flowers with no petals is most likely to be pollinated by
moths
wind
bees
bats
32
What do seedless plants produce instead of seeds?
spores
ovaries
milk
fruits
33
In what ways have plants evolved to resist being prey?
all of these
by producing poisons.
having trichomes, spikes, thorns, and spines.
producing sticky, sap when being attacked by insects.
34
In what order do the following taxa appear in the fossil record?
invertebrates, fish, amphibians, land plants
invertebrates, amphibians, fish, land plants
invertebrates, fish, land plants, amphibians
land plants, invertebrates, amphibians, fish
35
Which structure is ONLY found in angiosperms and NOT gymnosperms?
pollen
ovaries
vascular tissue
ovules
36
Is wind pollination an effective method?
Maybe
Who knows? This isn't measurable
Absolutely!
Absolutely not!
37

43
What is the main function of a fruit?
to poison animals
to disperse seeds away from parent plant.
all fruits provide food to animals
prevent embryos from getting radiation induced mutations
44
The evolution of seeds allowed
for the development of an independent sporophyte
plants to colonize dryer climates
