Question

The gametophyte of fern bears
A. True root
B. Antheridia
C. Archegonia
D. Both B and C

Answer 1

Hint: A fern is a type of vascular plant that reproduces with the help of spores and has neither seed nor flower. They are different from mosses in being vascular.

Complete step-by-step answer:
- True roots: True roots are present in the angiosperm in which vascular tissues are also present. They have seeds within the fruits. The fern has true roots as it does not produce flowers.
- Antheridia: Antheridia is found in the gametophytes phase of cytograms like bryophytes and fern. It is a haploid organ that produces male gametes known as antherozoids. Some algae and fungi also have antheridium as their reproductive stages. The antheridium has a sterile cell and spermatogenous tissue.
- Archegonia: Archegonium is the multicellular organs of gametophytes of a particular plant that produce ovum. The Archegonium has a long neck like structure which has a swollen base. It is located on the base of the thallus. The prothallus is the gametophytes of fern which has both the sex organ.
Hence, the correct option is D.

Note: The gametophytes of fern is a cellular structure which is of a single layer. Its main function is to form the gametes which show sporophytes generation.
