Chapter 31, Problem 2
Which of the following cells or structures are associated with asexual reproduction in fungi?
a. Ascospores
b. Basidiospores
c. Zygosporangia
d. Conidiophores
Verified step by step guidance1
Understand the concept of asexual reproduction in fungi. Asexual reproduction involves the production of offspring without the fusion of gametes, and it typically results in genetically identical organisms.
Identify the structures associated with asexual reproduction in fungi. Conidiophores are specialized fungal structures that produce conidia, which are asexual spores.
Ascertain the role of conidia in asexual reproduction. Conidia are formed on conidiophores and are dispersed to form new fungal colonies without sexual reproduction.
Differentiate between the options given: Ascospores and basidiospores are associated with sexual reproduction, while zygosporangia are involved in the sexual reproduction of zygomycetes.
Conclude that conidiophores are the structures associated with asexual reproduction in fungi, as they produce conidia, which are asexual spores.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Asexual Reproduction in Fungi
Asexual reproduction in fungi involves the production of spores without the fusion of gametes, allowing for rapid and efficient propagation. This process typically results in genetically identical offspring, enabling fungi to colonize environments quickly. Common structures associated with asexual reproduction include conidiophores, which produce conidia, a type of asexual spore.

Conidiophores
Conidiophores are specialized fungal structures that produce conidia, which are asexual spores. These structures are crucial for asexual reproduction, allowing fungi to disperse and reproduce without sexual processes. Conidiophores vary in shape and size among different fungal species, and they play a key role in the rapid spread of fungi in suitable environments.
Sexual Reproduction in Fungi
Sexual reproduction in fungi involves the fusion of specialized cells or spores, leading to genetic recombination and diversity. Structures like ascospores, basidiospores, and zygosporangia are associated with sexual reproduction, where genetic material from two parent cells combines to form a new organism. This process enhances adaptability and survival in changing environments.

Textbook Question
The grass Dichanthelium lanuginosum lives in hot soils and houses fungi of the genus Curvularia as endophytes. Researchers tested the impact of Curvularia on the heat tolerance of this grass. They grew plants without (E−) and with (E+) Curvularia endophytes at different temperatures and measured plant mass and the number of new shoots the plants produced. Draw a bar graph for plant mass versus temperature and interpret it.
