Some blue-green algae contain gas vacuoles that allow them to adjust the air concentration inside their cells. How does this internal gas vacuole benefit these organisms?

float

Explanation:

like a balloon or an air filled raft

it helps them float

Gas vacuoles help bacteria in buoyancy and enable them to float at the desired depth. They do so by inflating and deflating the vesicles
