15 points. which of the following best summarizes the process of fertilization of a gymnosperm? a) male and female gametes are produced in a single cone, with pollen on the outside and the egg within the ovule beneath the scales. pollen travels to the ovule, meets the egg, and fertilization can take place. b) cones are released from the tree and carried by wind to a moist environment where sperm can easily travel to the egg, and fertilization can take place. c) pollen travels from a male cone, the pollen becomes enclosed in the ovule that contains the egg within the female cone, the scale encloses the entire structure, and fertilization takes place. d) scales from male cones are carried to female cones, pollen is transferred to the female egg within the ovule, and fertilization takes place.

Which of the following best describes the male and female reproductive structures of an angiosperm? a) angiosperms produce flowers, inside which the male stamens hold the pollen and the female pistil holds the ovule. b) angiosperms produce male and female cones, and the pollen from a male cone fertilizes the egg inside a female cone. c) angiosperms produce male and female gametophytes, and the male gametophyte produces spores that fertilize eggs inside the female gametophyte. d) angiosperms produce sporangia, which release spores that develop into male flowers containing pollen and female flowers containing ovules.

Which of the following best compares the male and female reproductive structures of a gymnosperm? a gymnosperms produce flowers, and the male stamens produce pollen that fertilizes the egg inside the female ovule. b gymnosperms produce male cones and female cones, and the pollen from a male cone fertilizes the egg inside a female cone. c gymnosperms have male sporangia and female archegonia, and spores fertilize eggs contained inside the embryo sac to form zygotes. d gymnosperms exist as male and female gametophytes, and the male plant produces spores that fertilize eggs inside the female archegonia.
