Cells that doesn't have enough membrance-bound nucleus are called "Prokaryotes" That it passed down to the generations from greek meaning "Nuckei". Cells like these have few internal structures that are distinguishable under a microscope only, it cannot be seen by your eyes unless some engine to help you out. Cells in the "Monera" kingdom such as a bacteria and cyanobacteria, also are know with other name as "Blue-Green algae" are also prokaryotes.

These "Prokaryotic" cells differ significantly from "eukaryotic cells". they doesn't have membrane-bound nucleus and instead of having "Chromosomal DNA", their genetic information is in a circular loop called "plasmid".

Bacterial cells are very small, roughly the size of an animal mitochondrion, it is also about 1-2µm in diameter and 10 µm long. 

Prokaryotic cells feature three major shapes -

1. Rod shaped
2. Spherical
3. Spiral.

Instead of going through elaborate replication processes like "eukaryotes", bacterial cells divide by binary fission.
