Prokaryotic cells are the cells that do not possess a true nucleus. They do not even possess a membrane bound organelles. Organisms with in the domains bacteria and Archaea have prokaryotic cells. The other forms of life are the eukaryotic.
It is a unicellular organism. The word prokaryotic comes from a Greek word. The prokaryotic cells have a cell membrane or a plasma membrane which acts like a protective shield. Along with this, they also have a rigid cell wall which acts like further support and protection.
Prokaryotic cell are the most primitive type of organism that do not posses a true nucleus in them. They do not even have true membrane bound organelles.
The prokaryotes have plasma membrane as their protective covering which helps them to survive in extreme conditions.
They also posses rigid cell wall which also provides them protection and rigidity. Example: Archaea and bacteria.
These processes of breakdown and transport due to exposure to the environment are called weathering and erosion. Weathering and erosion affect all rocks on the earth's surface.
