◉ 1) Spores and gametes are both haploid reproductive cells. What
is the difference between the two?
,A) Spores germinate and grow into a multicellular haploid
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 asexually, and
gametes are found only in plants that reproduce sexually.
D) Gametes germinate and grow into a multicellular haploid
gametophyte, and spores carry out fertilization.. Answer: c

◉ Conifers do not have flowers to attract pollinators. Instead,
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.
