You are observing a gram stain of rod-shaped microorganisms that are linked in a chain and stain purple. how would you describe these bacteria using the correct terminology for the cell shape and arrangement?

according to the question, the observed microorganism have the following characteristics:

1. rod shaped.

2. linked in a chain.

3. stains purple.

The rod shaped bacteria are referred as the bacilli. The bacteria, which are found linked in a chain are given a prefix strepto. The bacteria, which stain purple with the gram stains are called gram positive bacteria.
