Which among the following produce seeds?
(a) Thallophyta
(b) Bryophyta
(c) Pteridophyta
(d) Gymnosperms
Answer- (d)
Solution- Gymnosperms do not produce flowers. The male and female gametophytes are present in the sporophyte. They produce seeds which are not present inside an ovary and are called as naked seeds. In bryophytes and pteridophytes, zygote produces sporophyte and there is no seed formation. In thallophyte, reproduction is mainly asexual and when sexual it is isogamous, anisogamous or oogamous.
The correct answer is d)- Gymnosperms
