The three bacterial shapes in Model 1 are referred to as coccus (sphere), spirillum, and bacillus (rod). Label the diagrams in Model 1 with the correct descriptions.

Bacteria keep their shape by having a rigid cell wall, but they can be shaped and appear differently. There are three main shapes of bacteria: 1.) The Coccus bacteria is in a sphere shape. 2.) Spirillum bacteria is in a spiral shape. 3.) The Bacillus bacteria comes in a rod shape. Each of these bacteria can come in pairs, clusters or chains.
