Answer
pteridophytes
Explanation
Solution
Pteridophyta is a group of non-seed forming, vascular cryptogams, i.e., these contain vascular tissues for the conduction of minerals and water but do not produce seeds. The main plant body of these plants is diploid called sporophyte which produces spores after meiosis. These spores on germination give rise to gametophytic plant which produces gametes. Fusion between male and female gametes produces a diploid zygote which produces diploid sporophytic stage.
