Which of the following events follows cell fusion in an ascomycete?
a. Conidiophore formation
b. Conidiospore germination
c. Ascus opening
d. Ascospore formation
e. Conidiospore release

검증된 단계별 안내

Understand the life cycle of ascomycetes, focusing on the sexual reproduction phase where cell fusion (plasmogamy) occurs.

Recall that after cell fusion, the next key event is karyogamy, where the nuclei fuse to form a diploid nucleus inside the ascus.

Following karyogamy, meiosis occurs within the ascus, leading to the formation of haploid ascospores.

Recognize that ascospore formation happens inside the ascus, making it the event that directly follows cell fusion.

Eliminate options related to asexual reproduction (conidiophore formation, conidiospore germination, and release) and ascus opening, which occurs after ascospore formation.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Cell Fusion in Ascomycetes

Cell fusion, or plasmogamy, is the process where two compatible fungal cells merge their cytoplasm without immediately fusing their nuclei. This event initiates the sexual reproductive cycle in ascomycetes and sets the stage for subsequent nuclear events leading to spore formation.

Ascospore Formation

Following cell fusion and nuclear fusion (karyogamy), the diploid nucleus undergoes meiosis to produce haploid nuclei, which develop into ascospores inside a sac-like structure called the ascus. Ascospore formation is a key step in the sexual reproduction of ascomycetes.

Conidiophore and Conidiospore Formation

Conidiophores are specialized hyphae that produce asexual spores called conidiospores. These structures and spores are involved in asexual reproduction and occur independently of the sexual cycle initiated by cell fusion in ascomycetes.
