Most prokaryotic cell particularly the bacterial cells have a chemically complex cell envelope. The cell envelope consists of a tightly bound three layered structure, i.e. the outermost glycocalyx followed by the cell wall and plasma membrane. Although each layer of the envelope performs distinct function, they act together as a single protective unit.

Assertion and Reasoning: Prokaryotes have a one envelop system.
Assertion (A): Prokaryotes have a one envelop system.
Reason (R): There is not even a single membrane that surrounds the prokaryotic cell.
Correct answer: Option (C) Assertion (A) is true but reason (R) is false.
Explanation:
Prokaryotes are unicellular organisms that lack a true nucleus and membrane-bound organelles. They are characterized by having a single circular chromosome and a cell wall that protects and shapes the cell. Prokaryotic cells have no nucleus or membrane-bound organelles such as mitochondria or chloroplasts. Instead, they have a single, circular chromosome located in a region called the nucleoid.
The cell envelope of prokaryotes is composed of three layers: the plasma membrane, the cell wall, and the outer membrane (in some bacteria). The plasma membrane is the outermost layer and surrounds the cytoplasm. It is composed of a phospholipid bilayer and proteins that regulate the movement of substances into and out of the cell.
The cell wall is located outside of the plasma membrane and provides structural support and protection for the cell. It is composed of peptidoglycan, a polymer of sugars and amino acids.
Therefore, the assertion that prokaryotes have a one envelop system is true because they have a single plasma membrane that surrounds the cytoplasm and a cell wall that provides additional protection and support. However, the reason given for this assertion is false. Prokaryotic cells do have a membrane that surrounds the cell, it is just not a double-membrane system like in eukaryotic cells.
Assertion (A): Prokaryotes have a one envelop system.
Reason (R): There is not even a single membrane that surrounds the prokaryotic cell.
Correct answer: Option (C) Assertion (A) is true but reason (R) is false.
