So the question we have is what are the two major reproductive adaptation seen in both gymnasperms and the angiosperm when compared to early non -viscular plants? well, you know, vesicular bundles are the xylem and the flume helps in the conduction of water, mineral, and food, right? so a vescular bundle present in heterofighter, gymnasperm, angiosperm, absent in.

Bryophytes, right? so the reproduction cycle of the bryophytes include there are two different stages in the life cycle of bryophytes.
00:40
One is the chemitophyte, it's a sporophyte.
00:45
The plant body of bryophytes is chemotophyte, haploid, right? sex organs are formed on chemotophyte.
00:54
Male sex organs is called entreatia and female sex organ is called archygonia.
01:00
Right so male gamete are formed in antheroid which is bioflageate and motile in bryophyta male gamete reaches the female gamete and fertilizes it so as a result of fertilization a deployed zycod was formed this psych would initiates the sporophytic generation for example deployed stage in in priofiter, the spheroophytes dependent on gametophyte.

In briophyta, there is no formation of fruit and the seed, right? reproductive adaptations seen in gymnosperm and engeosperm...
