what are the charecteristics of prokaryotic cell for 4 marks pls answer it fast
Answers
Answer:
Your Answer is here:-
Explanation:
•Prokaryotes lack an organized nucleus and other membrane-bound organelles.
•Prokaryotic DNA is found in a central part of the cell called the nucleoid.
•The cell wall of a prokaryote acts as an extra layer of protection, helps maintain cell shape, and prevents dehydration.
• Some prokaryotic cells may also possess flagella.
Answer:
Components of Prokaryotic Cells
All cells share four common components:
a plasma membrane: an outer covering that separates the cell’s interior from its surrounding environment.
cytoplasm: a jelly-like cytosol within the cell in which other cellular components are found
DNA: the genetic material of the cell
ribosomes: where protein synthesis occurs
However, prokaryotes differ from eukaryotic cells in several ways.
A prokaryote is a simple, single-celled (unicellular) organism that lacks an organized nucleus or any other membrane-bound organelle. We will shortly come to see that this is significantly different in eukaryotes. Prokaryotic DNA is found in a central part of the cell: the nucleoid.
Most prokaryotes have a peptidoglycan cell wall and many have a polysaccharide capsule. The cell wall acts as an extra layer of protection, helps the cell maintain its shape, and prevents dehydration. The capsule enables the cell to attach to surfaces in its environment. Some prokaryotes have flagella, pili, or fimbriae. Flagella are used for locomotion. Pili are used to exchange genetic material during a type of reproduction called conjugation. Fimbriae are used by bacteria to attach to a host cell.
