Final answer:
Fungi that produce swimming cells are likely referring to oomycetes. Oomycetes are nonphotosynthetic organisms that have a cellulose-based cell wall and flagella for locomotion.
Step-by-step explanation:
Fungi that produce swimming cells are likely referring to oomycetes. Oomycetes are not closely related to true fungi, but they have a similar morphology. They have a cellulose-based cell wall and a network of filaments for nutrient uptake. Many oomycetes have flagella for locomotion, making them capable of swimming. They are nonphotosynthetic and include both saprobes and parasites.
