Can someone please explain the life cycle of Ascomycota fungi?

..I'll report it tomorrow..please, someone expalain it to me clearly. the whole process..etc.plz..Can someone please explain the life cycle of Ascomycota fungi?
ascomycota fungi also known as sac fungi, because they form a sac, reproduce asexually through spores. when the spores germinates into hyphae they attract other hyphae from the same ascomycete species but from different mating types. they fuse and form a structure containing many independent nuclei, heterokaryotic hyphea. a short heterokaryotic hapae, containing one nucleus from each parent, emerges and eventually grows into a complex reproductive structure with a distinctive cell called the ascus (sac). after the two nuclei in the heterokaryotic cell fuse inside the sac, meiosis takes place and haploid spores are produced. when the ascus matures, its splits and the spores are released. then the cycle is repeated.
