Question

Quizplus · Accepted Answer

Yeasts can absorb nutrients directly across their cell surfaces, which is one of the characteristics that distinguishes them from other fungi. Yeasts are also unicellular and reproduce asexually by budding or fission, but not all yeasts undergo a multicellular stage or are dikaryotic. They are not necessarily a monophyletic group, as some fungi that are not yeasts can also reproduce asexually by budding. Therefore, choices A, B, D, and E are not entirely true.
