Cyanobacteria are unicellular which means that they

• are made of multiple cells

• are made of only one cell

• are not made of cells

The Great Oxygenation event was caused by a change in oxygen composition in the atmosphere, where the amount of oxygen:

• Stayed the same

• Increased

• Decreased

Before cyanobacteria, oxygen on Earth was:

• Locked in molecules

• Locked in the ocean

• Not present on Earth

• In the atmosphere in low concentrations

Cyanobacteria are known for their ability to perform this process, which is crucial for life on Earth.

• Photosynthesis

• Respiration

• Fermentation

• Nitrogen fixation

The pigments responsible for the blue-green color of cyanobacteria are called:

• Chlorophyll

• Carotenoids

• Phycobilins

• Xanthophylls
