A Prokaryotic cell does not contain a nucleus. It only contains one chromosome and is a single-celled organism. It was the only form of life on earth for millions of years. Examples of a Prokaryotic cell are the different types of bacteria present today. A Eukaryotic cell contains a nucleus; more than one chromosome and is typically a multi-celled organism. <span>Both plant and animal cells are eukaryotic cells.</span>
The characteristic feature of prokaryotes cells is that they lack the nucleus.
Further Explanation:
An ecosystem is made up of mainly two kinds of cells:
Eukaryotes cells: They mainly consist of a group of animals, fungi, and plants.
Prokaryotes cells: They mainly consist of bacteria and archaea.
The single-celled organisms such as bacteria and archaea are the prokaryotes. Cyanobacteria are an example of prokaryotes that synthesize their own food by the process of photosynthesis. The cellular organization of prokaryotes is very simple. Some main features of prokaryotic cells are:
They don’t possess membrane-bound organelles and nucleus
The DNA of a prokaryotic cell is found in the cytoplasm of the cell which is mainly called the nucleoid.
The size of the cells is around 0.1 to 5.0μm in diameter.
The prokaryotic cell wall provides more protection than the eukaryotic cell wall. They also maintain the shape of the cell and provide protection against dehydration.
