The ANSWER is:
Assuming ur doing SOS:
In organisms that most often reproduce asexually, the product of sexual reproduction is often more resistant to unfavorable environmental conditions than the individual of the species produced by mitosis. Some kinds of protists such as protozoans and algae do not usually reproduce sexually unless growing conditions have become unfavorable. Many plants do not produce seeds until the approach of winter or a dry period of the year.
Sexual reproduction is defined as the fusion of male and female gametes to give rise to the organism. Sexual reproduction leads to diversity and variation. However, some asexually reproducing organisms undergo sexual reproduction.
The organisms reproducing asexually switch to sexual reproduction as:
1. Algae and fungi reproduce asexually, a mode of reproduction in which the organisms are genetically similar to the parent.
2. The algae and fungi switch to a sexual mode of reproduction because of the adverse conditions of the environment.
3. Sexual reproduction leads to diversity and variation that help the offspring to be better suited and sustained to the environment, having higher chances of survival.
Thus, during adverse conditions, the organisms like fungi shift to the sexual mode for the better survival of their offspring.
