Bryophytes and pteridophytes do not show similarity in which one of the following feature?
1 Haplo-diplontic alternation of generation
2 Meiosis in sporophyte
3 Main gametophytic plant body
4 Dependence on water for fertilisation
Explanation:
In bryophytes, gametophyte is the main plant body. Whereas, in pteridophytes, sporophyte is the main plant body.

To which of the groups would you assign plant which has a primitive vascular supply but does not produce flowers and grown as ornamentals?
1 Gymmosperms
2 Pteridophyta
3 Bryophyta
4 Algae
Explanation:
Pteridophytes, frequently grown as ornamentals are the first plants to possess vascular tissues. They don’t bear flowers.

In homosporous pteridophyte, the gametophyte is
1 Neither monoecious or dioecious
2 May be monoecious or dioecious
3 Dioecious
4 Monoecious
Explanation:
The spores when are present in homosporous condition (in both male and female parts only one type of gametophyte is present) then the gametophyte produced is called monoecious but when the spores are present in heterozygous condition (male an female parts produce different gametophytes, the male produces microspores while female produces megaspores) then the gametophyte produced is called dioecious.

Which one is/are correct about heterosporous pteridophytes?
1 The female gametophytes are retained on the parent sporophyte for variable period
2 Microspore and megaspores develop into the male and female gametophytes respectively
3 The development of the zygote into the embryo takes place within female gametophyte
4 All of these
Explanation:
The female gametophytes are retained on the parent sporophyte for variable period. Microspore and megaspores develop into the male and female gametophytes respectively. The development of the zygote into the embryo takes place within female. All are correct regarding heterosporus pteridophyta.
