Question

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.

Answer 1

Answer: Gymnosperms produce male cones and female cones, and the pollen from a male cone fertilizes the egg inside a female cone.

Answer 2

Answer: B Gymnosperms produce male cones and female cones, and the pollen from a male cone fertilizes the egg inside a female cone.

Gymnosperms are terrestrial plants, which lacks flowers. The ovule or seeds are remains naked in hard woody structures called as cones. In the gymnosperms the green sporophyte generates cones that contains male and female gametophytes. A male cone consists of microsporophylls where male gametophyte also called as pollen are produced and released into the wind. The wind act as a agent for pollinating the female gametophyte present in the female cone. Inside the female cone the megaspore mother cell produces four haploid megaspores, one megaspore divide itself to form the female gametopyte. The fusion of the pollen with the female gametophyte produces diploid zygote, which later on divides to form the embryo.
