Question

a prokaryotic cell does not process
a. cell membrane
b. cell wall
c. nuclear membrane
d. both , a and c​

Answer 1

Answer:

Prokaryotic cells lack a well-developed or membrane-bound nucleus and cellular organelles.

They also lack the cytoskeleton (microtubules, microfilaments) in the cytoplasm, therefore, they don't have centrioles.

They also lack desmosomes (a cellular structure which is a modification of the cell membrane) for cell-to-cell adhesion.

Answer 2

The Correct solution is Option C, Nuclear membrane.

• Characteristics of Prokaryotes:-
• The nucleoid is the core part of the cell that houses the cell's DNA.
• Protein synthesis is carried out by ribosomes. A "true" nucleus is absent in prokaryotes i.e the nuclear material is devoid of the nuclear membrane and nucleolus and other membrane-bound organelles are also not found in the cytoplasm.
• In certain bacteria, the cell wall in addition to the cell membrane gives the cell structure and protects it from the outside environment. Peptidoglycans are a type of cell wall made up of carbohydrates and proteins that most bacteria contain. The individual units are N acetyl glucosamine and N acetyl muramic acid.
• The cell membrane, also known as the plasma membrane, separates the cell from the outside surroundings in every prokaryote.
• The capsule is a coating of carbohydrates that surrounds the cell wall in some bacteria. The bacterium may attach to other cell surfaces because of the capsule.
• Fimbriae are hair-like structures that aid in cell adhesion.
• Pili are rod-shaped structures that play a variety of activities, including DNA transfer and adhesion.
• Flagella are tail-like structures that help in bacterial movement.
