`color{blue} ul(mathtt ("Prokaryotes))` : A prokaryote is a unicellular organism that lacks a `color{Violet}"membrane-bound"` nucleus (karyon), mitochondria, or any other membrane-bound organelle. The word prokaryote comes from the Greek (pro) "before" and (`color{Violet}"karyon"`) "nut or kernel".
`color{blue} ul(mathtt ("Eukaryotes))` : A eukaryote is any organism whose cells have a nucleus and other organelles enclosed within membranes.

● All the monerans are `color{Violet}"prokaryotic"` (primitive nucleus) and microscopic.
Bacteria has a chemically complex cell envelope consist of a tightly bound 3 layered structure:
(1) Outermost `color{Violet}"glycocalyx"` (may be capsule thick and tough or slime layer- loose sheath)
(2) Cell wall- non cellulosic and rigid made up of mainly `color{Violet}"peptidoglycan or murein"` which is a type of mucopeptide .
(3) Cell membrane- Made up of `color{Violet}"lipoprotein"`
Based on the structure of cell wall, bacteria are either `color{Violet}"gram positive or gram negative"`. The differences are given below:
● They are either single celled or form colonies
● Bacteria are grouped under four categories based on their shape.
● They are as follows:
