Question

How do you describe the cell morphology of Escherichia coli?

Answer 1

Morphology of Escherichia coli:

1. It is commonly found in the lower intestine of our digestive system.
2. It is a rod-shaped bacteria.
3. It is about 2.0 μm long and 0.25–1.0 μm in diameter.
4. Its envelope is composed of 3 layers – peptidoglycan, cytoplasmic membrane, and outer membrane.
5. It is a Gram-negative bacteria.
6. So, during the staining, E. coli picks up the colour of the counterstain safranin and stains pink.
