Gram positive bacteria differ from gram negative bacteria in the structure of their
A) Nucleoid
B) Cytoplasm
C) Cell wall
D) Ribosomes

Hint:Bacteria are tiny, single-celled bions that grow in several circumstances. These bones can live in dirt, the sea and inside the human stomach. Humans' contact with bacteria is complex. Sometimes bacteria give us helping support, such as by coagulating milk into yoghurt or assisting with our metabolism.

Complete answer:
>Option A: Both Gram-positive and negative bacteria are defined by the lack of membrane-bound valid nucleus and appearance of their inheritance material in the middle of the cell as the nucleoid. Therefore, this is an incorrect answer.
>Option B: The cytoplasm, of bacterial cells, is where the roles for cell development, metabolism, and replication are taken place. Therefore, this is an incorrect answer.
>Option C: The gram-negative cell wall is defined by the appearance of an outer layer, a more fragile peptidoglycan layer and large periplasmic space encompassing the peptidoglycan.
Gram-positive cells are defined by the behaviour of a single thick membrane of cell wall which is formed up of peptidoglycan, lipoteichoic acid and teichoic acid. They want the outer layer and porin and have a small periplasmic area. Therefore this is the correct answer.
>Option D: Ribosomes are the place for protein structure and hold two subunits; big and small. Prokaryotic ribosomes ought the 30S and 50S subunits that collectively make a 70S ribosome.
Both Gram-positive and negative bacteria have unit cell layers of 70S ribosomes and phospholipids.
Therefore, this is an incorrect answer.

Thus, option C is the correct answer.

Note:The other differences between Gram negative and Gram positive bacteria are,
>In gram positive the outer membrane is absent while it is present in gram negative.
>Mesosomes are more prominent in gram positive than gram negative.
>Gram positive appears as violet colour when stained and gram negative appears as pink colour.
