The DNA of a prokaryote exists as as a single circular chromosome. Prokaryotic cell size ranges from 01 to 50 μm in diameter.

At first I was convinced that it was cyanobacteria however a classmate said it look more like a little worm and other person said it look like it was probably nothing nor prokaryote nor worm.
IS PROKARYOTE SMALL. The cell wall of a prokaryote acts as an extra layer of protection helps maintain cell shape and prevents dehydration. What is the smallest prokaryote. Prokaryotic and Eukaryotic cells are both alive while viruses are not.
A prokaryotic cell is a simple single-celled unicellular organism that lacks a nucleus or any other membrane-bound organelle. In the following photos can be seen a thread-like almost like longkou vermicelli things. 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.
They contain a plasma membrane cell wall RNA or DNA and a protein capsule. A feature often used to distinguish prokaryotic and eukaryotic genomes is the amount on junk DNA noncoding DNA that is probably largely remnants of genes that have been lost over the course of evolution. Dialister pneumnosintes are the smallest prokaryotes.
Prokaryotic cell size ranges from 01 to 50 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. Eukaryotic organisms may be multicellular or single-celled organisms.
The prokaryote now enlarged is pinched inward at its equator and the two resulting cells which are clones separate. The name prokaryote came from Old Greek. Organisms having prokaryotic cellular organisations are both unicellular as well as multicellular.
Also what type of cell is a virus. Some prokaryotes have flagella pili or fimbriae. 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.
As a general rule prokaryotes tend to have very little junk DNA. When a prokaryote grows to a large size the process of binary fission takes place. The most common bacteria shapes are spherical rod-shaped and.
A darkened region called the nucleoid Figure 1. Karyon nut or kernel referring to the cell nucleus. Bacteria are unicellular but cyanobacteria have multicellular forms.
Prokaryotic DNA is found in the central part of the cell. Bacteria and cyanobacteria are the typical representatives of prokaryotic cells. They have no true nucleus as the DNA is not contained within a membrane or separated from the rest of the cell but is coiled up in a region of the cytoplasm called the nucleoid.
Rather the chromosome is replicated and the two resulting copies separate from one another due to the growth of the cell. Most prokaryotes carry a small amount of genetic material in the form of a single molecule or chromosome of circular DNA. The DNA in prokaryotes is contained in a central area of the cell called the nucleoid which is not surrounded by a nuclear membrane.
A small molecule of DNA that can reproduce independently. Prokaryotic organisms have varying cell shapes. Prokaryotic cell size ranges from 01 to 50 μm in diameter.
Further there are no organelles so there is nothing to divide. The smallest free-living organisms have a genome size over 1 Mbp. Eukaryotes are organisms made up of cells that possess a membrane-bound nucleus that holds DNA in the form of chromosomes as well as membrane-bound organelles.
Prokaryotic cells have only a small amount of DNA which is not stored in complex chromosomes. Viruses are much much smaller than prokaryotes. Viruses have very few organelles similar to the prokaryotic cells.
Prokaryotic cells tend to be small simple cells measuring around 01-5 μm in diameter. Bacteria and archaea are two major branches of prokaryotes. Prokaryotes do not undergo mitosis.
Prokaryote or just a small worm. Prokaryotic cells are not as complex as eukaryotic cells. Why do prokaryotes not have nucleus.
The cell wall of a prokaryote acts as an extra layer of protection helps maintain cell shape and prevents dehydration.
