Hungry Green Algae Will Eat Live Bacteria
The hungry green algae seeks out energy through phagocytosis.

They then combined the bacteria with five strains of unicellular green algae called prasinophytes inside a flow cytometer, which helps scientists analyze cell properties in solution. The flow cytometer measured increasing levels of green fluorescence in the algal cells over time, suggesting that the algae were consuming the glowing bacteria. To confirm that ingestion was actually occurring, they peered inside of the algal cells with high-precision microscopy.
