Question

Fungi are able to reproduce asexually by creating conidiospores and sporangiospores. Which of the following is an accurate explanation for why it is advantageous that they are also capable of sexual reproduction?

1) Asexually produced offspring are more likely to compete for resources and will kill off the parental fungi.
2) Fungi normally produce sexually but produce asexually in harsh conditions such as severe drought.
3) Offspring from two parents may have variations in form and function that contribute to survival of the species.
4) Sexual reproduction produces more offspring at a faster rate than spore formation.

Answer 1

The advantage of fungi also being capable of sexual reproduction is that it allows the production of offspring with genetic variations, which may enhance survival in changing conditions. Sexual reproduction combines traits from two different parental strains, resulting in increased genetic diversity and adaptability.

Step-by-step explanation:

Fungi have the capability to reproduce both asexually and sexually. Asexual reproduction is a rapid process allowing fungi to spread when environments are favorable. However, sexual reproduction is also significant because it increases genetic diversity.

The correct explanation for why it is advantageous for fungi to also be capable of sexual reproduction is: Offspring from two parents may have variations in form and function that contribute to survival of the species. This genetic variation is crucial during changing or unfavorable environmental conditions, as it may lead to the survival of offspring that can handle the new conditions better than their parents could. Conidiospores and sporangiospores produced asexually are generally clones of the parent, while sexual reproduction involving spores from two genetically distinct parents often results in genetically unique offspring.

In harsh conditions, like severe drought, two mating types of fungi (+ and -) may produce gametangia that fuse to form a zygospore, which has a thick coat for protection and can remain dormant until the environment becomes favorable again. Sexual reproduction can create new, potentially more resilient strains, helping the species to adapt over time.
