◉ Ferns and mosses need water for sexual reproduction because:
Answer: they have swimming sperm.
◉ An oak tree is a:
Answer: sporophyte.
◉ The embryo sac of angiosperms consists of eight diploid cells and
one haploid egg cell. True or False?
Answer: False
◉ The male reproductive structure, the stamen, consists of:
Answer: the filament and anther.
◉ Meiosis produces a ___, which eventually gives rise to an egg in an
unfertilized seed.
Answer: megaspore
,◉ What undergoes meiosis during the development of pollen
grains?
Answer: microspore mother cell
◉ All of the following are processes that occur during angiosperm
reproduction EXCEPT:
- the generative cell forms two sperm cells via mitosis.
- the megaspore mother cell undergoes meiosis to produce four
haploid megaspores.
- the microspore mother cell undergoes meiosis to produce four
haploid microspores
- one megaspore degenerates, and the other three divide once to
produce the six-celled embryo sac.
- the tube cell produces the pollen tube.
Answer: one megaspore degenerates, and the other three divide
once to produce the six-celled embryo sac.
◉ In flowering plants, the unfertilized ovule contains the:
Answer: female gametophyte.
◉ Endosperm has allowed the angiosperms to become the most
numerous and diverse plant group. What is the role of the
endosperm?
, Answer: It provides nutrition for the developing embryo, therefore
increasing survival rates.
◉ A fruit is a mature:
Answer: ovary.
◉ What is endosperm?
Answer: via cotyledons, a source of food for the embryo
◉ A diploid cell develops in to the
____.
Answer: embryo
◉ Fruits evolved primarily as structures specialized to ___.
Answer: disperse seeds
◉ In north-central Florida, the cars, homes, streets, and ponds are
covered with an impressive coating of bright yellow dust every
spring. Upon closer, microscopic examination, the yellow "dust"
turns out to be pollen grains. This area of Florida has pine trees,
showy daytime-flowering plants, and often-unnoticed nighttime-
flowering plants releasing pollen at the same time of year.
