If a bacterial cell has a length of 0.9 micrometers (µm), how many nanometers (nm) long is the cell?

900 nanometer (nm)

Explanation:

Given that,  

Length of a bacterial cell = 0.9 micrometer (µm)

There is a direct relationship between the nanometer and the micrometer scale,

It is that 1 micrometer (μm) = 1000 nanometer (nm)

Therefore, 0.9 μm = 900 nm

Thus, the length of the given bacterial cell is 900 nanometer (nm).

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
