Which of the following characteristics can distinguish bacterial cells from cells in the other domains of life
SVETLANKA909090 [29]

The characteristic that can distinguish bacterial cells from cells in the other domains of life is that only bacterial cells have peptidoglycan cell wells.

What is the major difference between a bacterial cell and the cells of other organisms?

Animal and plant cells are different from bacterial cells in a number of ways. One key distinction is that, unlike plant and animal cells, bacterial cells lack internal organelles including mitochondria, chloroplasts, and a nucleus.

Bacteria can be categorised according to their morphology, such as bacilli (rod-shaped), cocci (sphere-shaped), and spirilli (spirals). In that they have cytoplasm, ribosomes, and a plasma membrane, bacteria resemble eukaryotic cells. A bacterial cell can be distinguished from a eukaryotic cell by its circular nucleoid DNA, absence of membrane-bound organelles, peptidoglycan cell wall, and flagella.
