Study with Quizlet and memorize flashcards containing terms like Which fungi group is known as the zygote fungi and produces spores in zygosporangia?, Some protists form long, foot-like projections of their cell membrane and cytoplasm that are used for movement and to capture food. In the asexual life cycle, a haploid (1n) mycelium undergoes mitosis to form spores.2. 1. This form of sexual reproduction in fungi is called conjugation (although it differs markedly from conjugation in bacteria and protists), giving rise to the name "conjugated fungi". Zygosporangium and sporangium are both structures associated with the reproductive processes of certain organisms, but they serve different functions and appear in different contexts. This microbes lack reproduction phase, and they do not fit into the known taxonomic classifications of fungi , however Rhizopus.
