Practice question

Ascomycota produce sexual meiospores termed ascospores typically eight per ascus following meiosis plus one mitotic division inside sac. Ascospores form endogenously within sac-like ascus often arranged linearly or irregularly, wall contains melanin and hydrophobins resisting desiccation and UV. Upon maturation asci rupture or forcibly shoot spores via turgor pressure mechanism. Basidiospores exogenous on basidia externally, zygospores thick-walled diploid resting spores in mucorales, conidia asexual mitospores. Ascospore morphology - shape, septation, ornamentation - aids generic identification. Presence inside asci defines Ascomycota encompassing morels, truffles, yeasts, dermatophytes, many plant pathogens like powdery mildews.
