Answer
Sporophyte⇒sporangium⇒(meiosis)⇒haploidspores⇒gametophyte⇒gametongium⇒(mitosis)⇒eggs/sperm⇒(fertilization)⇒Diploid zygote⇒Sporophyte
Hence,gametophyte develop to gametongium to form the gametes through mitosis.
Sporaphyte develop to sporangium and through meiosis haploid spores are formed.
Step-by-step explanation
The sporangium in a diploid sporophyte is involved in the meiosis process to produce haploid spores.The haploid spores mature into haploid gametophyte.The female and male reproductive organs are involve in mitosis to produce haploid gametes.The gametes are involved in fertilization process to form a diploid zygote that undergoes growth and development to mature into a sporophyte.The cycle is initiated again.
