Researchers observed the zoosporic stage of the algae under the microscope to study its motility.

Under the microscope, we observed zoospores swimming toward nutrients released by the decaying leaf.

Under the microscope, the zoospore propelled itself with a single flagellum toward the nutrient-rich area.

The zoosporous algae released a stream of motile spores when the water temperature rose.

The research team developed a zoosporicidal compound that halted the fungal outbreak in greenhouse crops.
