Answer: sexual

Flashcard 52: In _____, the fungi have a predilection to proliferate in blood vessel walls, especially where there is excess glucose and ketone bodies

Answer: Mucormycosis

Flashcard 53: _____, Dermatophytes and Aspergillus are classified as Molds/filamentous fungi

Flashcard 55: _____ is the most common cause of fungal meningitis

Answer: Cryptococcus

Flashcard 56: Classification of fungi based on spore formation: Zygomycota reproduce by _____ spores called sporangiospores

Answer: asexual
