Answer:
D.asexual
Step-by-step explanation:
Asexual reproduction of plants takes place with the help of specialized haploid cells, spores. In a dispute, the sexes do not differ. The organism that forms spores is called a sporophyte.
Isosporic plants form all the same spores, from which a bipolar gametophyte develops, which creates both types of gametes, male and female.
