Question

The prokaryotic cells are characterized by _______
A).A distant nuclear membrane
B).Distinct chromosomes
C).Absence of chromatin material
D).Absence of nuclear membrane

Answer 1

Hint: A prokaryote is a simple, single-celled i.e. unicellular organism that has a deficit of an organized nucleus or any other membrane-bound organelle. Almost all prokaryotes have a peptidoglycan cell wall and many have a polysaccharide capsule. The cell wall acts as an extra layer of shield, helps the cell maintain its shape and prevents dehydration.

Complete answer:
Let’s discuss the options and find out the correct answer.
The capsule enables the cell to bind to surfaces in its environment. Some prokaryotes have flagella, pili, or fimbriae. Flagella are used for locomotion. Exchange genetic material during a type of reproduction called conjugation is used by pill. Fimbriae are used by bacteria to tie up to a host cell. Prokaryotes are deficient of an organized nucleus and other membrane-bound organelles. Prokaryotic DNA is found in a central part of the cell called the nucleoid.

 So, the correct answer is option A i.e prokaryotic cells are characterized by a distant nuclear membrane.

Note: The cell wall of a prokaryote acts as an extra layer of safety, helps maintain cell shape, and prevents dehydration. The size of a Prokaryotic cell extends from 0.1 to 5.0 μm in diameter. The micro size of prokaryotes allows quick access and diffusion of ions and molecules to other parts of the cell while also allowing quick removal of waste products out of the cell.
