Question

Among the cell structures and materials of bacteria listed below, which one would be innermost if arranged in proper order?
A. Glycocalyx
B. Plasma membrane
C. Primary cell wall
D. Secondary cell wall

Answer 1

Hint: Dissimilar to the eukaryotic cells, bacteria do not have a layer encased core. The chromosome, a solitary, consistent strand of DNA, is limited, yet not contained, in a district of the cell called the nucleoid. The wide range of various cell segments is dispersed all through the cytoplasm.

Complete answer: 

> The plasma membrane is the innermost and dynamic structure of a prokaryotic cell. Its primary function is a penetrable obstruction that controls the entry of substances into and out of the cell. The plasma membrane is the complete structure of a cell since it sequesters the particles of life in a unit, isolating it from the climate.
> The bacterial layer permits entry of water and uncharged particles up to MW of around 100 Daltons. However, it does not permit a section of bigger atoms or any charged substances aside from by implies uncommon membrane transport cycles and transport frameworks. 

So, the correct answer is “Option B”.

Additional Information:
> The glycocalyx is an exceptionally charged layer of membrane-bound natural macromolecules appended to a cell layer. This layer functions as an obstruction between a cell and its encompassing.
> The primary cell divider is a dainty, adaptable, and extensible layer of the cell divider made from cellulose, gelatin, and hemicellulose. It contains more gelatin than the auxiliary cell divider.
> The secondary cell divider is found in many plant cells, situated between the primary cell divider and the plasma membrane. The cell begins delivering this cell divider after the primary cell divider is finished, and the cell has quit growing.

Note: The plasma membrane or bacterial cytoplasmic layer is made out of a phospholipid bilayer and in this way has the entirety of the overall elements of a cell membrane, for example, going about as a porousness boundary for most particles and filling in as the area for the vehicle of atoms into the cell. Not with standing these capacities, prokaryotic layers likewise work in energy preservation as the area about which a proton thought process power is created.
