5. 1) Spores and gametes are both haploid reproductive c
cells. What is the difference between the two?
A) Spores germinate and grow into a multicellular hap-
loid gametophyte, and gametes fuse to form a diploid
zygote.
B) Spores fuse to form a diploid zygote that eventually
becomes the sporophyte, gametes.
C) Spores are found only in plants that reproduce asex-
ually, and gametes are found only in plants that repro-
duce sexually.
D) Gametes germinate and grow into a multicellular
haploid gametophyte, and spores carry out fertiliza-
tion.

when a spore germinates?
A) A plant that produces spores when mature.
B) An increased number of spores.
C) A plant that meiotically produces sex cells.
D) A haploid stage called the gametophyte.
E) A haploid stage called the sporophyte.
7. 13) ________ results in the production of spores in flow- B
ering plants.
A) Fertilization
B) Germination
C) Meiosis
D) Spermatogenesis

E) digestion of the seed coat.
9. 18) A pollen grain is actually the A
A) male gametophyte.
B) female gametophyte.
10. Conifers do not have flowers to attract pollinators. In- A
stead, fertilization occurs
A) via wind pollination.
B) as the sperm and egg unite inside the woody cone.
C) when the endosperm takes the place of the male
gametes.
D) when insects coated with pollen are trapped in the
sticky resin.
E) when birds transfer pollen in their droppings after
eating the pine seeds.
11. Grass flowers lack petals and sepals. Which of the fol- d
lowing statements is TRUE?
A) These flowers are pollinated at night, so they don't
benefit from showy petals or sepals.
B) They are pollinated by flies, which don't require
showy, scented petals.
C) They are imperfect flowers lacking stamen or
carpals.
D) They are incomplete flowers lacking one or more
floral parts.
