Which of these plants is correctly matched with its reproductive characteristics?
(i) Sphagnum: Male sex organs called antheridium produce biflagellate antherozoids while the female
sex organ called archegonium produces a single egg.
(ii) Sequoia: One of the megaspores enclosed within the megasporangium develops into a multicellular
female gametophyte that bears two or more archegonia or female sex organs.
(iii) Wolffia: One of the male gametes fuses with the egg cell to form a zygote while the other male
gamete fuses with the diploid secondary nucleus to produce the triploid primary endosperm nucleus.
(iv) Polysiphonia: Sexual reproduction is oogamous with non-motile gametes and accompanied by
complex post fertilization developments.
