Q.

Which among the following statements is false about pteridophytes?

1. Members of pteridophyta are homosporous or heterosporous

2. The sporophytes of pteridophytes produce the sex organs

3. Ferns exhibit circinate vernation

4. Sporophytic generation is dominant in pteridophytes

Q. Read statement ${}^{\prime }a$ to $d^{\prime }$ and find out how many is/are incorrect statement(s).
(a) In majority of the pteridophytes, all the spores are of similar kinds.
(b) Genera like Selaginella and Salvinia produce two kind of spore.
(c) The development of the zygote in the young embryos take place within the female gametophytes. This event is a precursor to the seed habit.
(d) Azolla is an aquatic fern that is used as biofertilizer due to the presence of nitrogen fixing cyanobacteria.
