Question

write two characteristics of prokaryotic cell?​

Answer 1

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.
Prokaryotic cell size ranges from 0.1 to 5.0 μm in diameter.
The small size of prokaryotes allows quick entry and diffusion of ions and molecules to other parts of the cell while also allowing fast removal of waste products out of the cell.
Key Terms
eukaryotic: Having complex cells in which the genetic material is organized into membrane-bound nuclei.
prokaryotic: Of cells, lacking a nucleus.
nucleoid: the irregularly-shaped region within a prokaryote cell where the genetic material is localized
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.

Answer 2

Answer:

The characteristics of a prokaryotic cell is as follows :

• The DNA is naked and lies variously coiled in the cytoplasm.
• The cell wall is present in bacteria and cyanobacteria and absent in mycoplasma.
• The flagella can be seen in some of the bacterias.
• The blue green algae and some bacteria are photoautotrophic.
• The prokaryotic cells lack mitochondria, endoplasmic reticulum, Golgi apparatus.
• It also lacks lysosomes, microtubules, microfilaments and centrioles.
• They contain complex vacuoles.
• They contain 70s ribosomes.
• The prokaryotes have single membrane and are called to have one envelope system.
• The DNA content is low.
• The transcription and translation occurs inside the cytoplasm.
• The respiratory enzymes are usually in contact with cell membrane
