Solution(By Examveda Team)

0.5 × 1.0 - 1.5μ is the average size of a bacteria.
Bacteria are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms.
Bacteria display a wide diversity of shapes and sizes. Bacterial cells are about one-tenth the size of eukaryotic cells and are typically 0.5 - 5.0 micrometers in length.
