What are the differences between prokaryotic and eukaryotic cells?
The differences between prokaryotic and eukaryotic cells, One of the most fundamental you’ll learn in biology class. In order to understand it, we need to take a closer look at what each of these two cell types is, how they differ from each other, and why their differences are so important to your health. Let’s get started!
what is prokaryotic cell?
A prokaryote is a microorganism, a single-celled organism that does not contain any membrane-bound organelles. These organisms are sometimes referred to as single-celled or simple living organisms, but some species of bacteria may actually be more complex than multicellular eukaryotes. The prokaryotes are thought to have evolved before eukaryotes did, which accounts for their lack of organelles.

What is eukaryotic cell?
The largest differences between prokaryotic and eukaryotic cells are found in their membrane-bound structures. While prokaryotes have just one cell membrane, eukaryotes have multiple membranes bounding their nucleus, a feature that makes them far more complex.
1. Size
The differences between prokaryotic and eukaryotic cells are most obvious when we compare cell size. The largest prokaryote cell is about one micrometer (1/1000 of a millimeter) in diameter about ten times smaller than an average human red blood cell. The biggest eukaryote is about 50 times larger than that, approaching unicellular-sized organisms like yeast or large amoebas.
2. Shape
- Although prokaryotes (one-celled organisms) have a wide variety of shapes, they are often elongated. This is because prokaryotes are generally smaller than eukaryotes, which generally have more volume.
- Because prokaryotes need less space, they can achieve a wider variety of forms. In comparison, eukaryotes usually have spherical or oblong bodies that help maintain their larger volumes.
3. Nucleus
The nucleus is a unique feature of eukaryotic cells. In prokaryotes, genetic material is not contained in a special, discrete organelle instead, it’s found throughout the cell’s cytoplasm. Because all of an organism’s chromosomes are sequestered into one small part of its structure, eukaryotes are able to form more complex organisms than prokaryotes.
4. Organelles
The organelles found in eukaryotic cells, such as mitochondria, chloroplasts, and Golgi apparatus are also present in prokaryotes. However, these organelles look completely different.
Also, there are no endomembranes in prokaryotes because they lack a cell membrane. The other biggest difference between prokaryotes and eukaryotes is that most prokaryote DNA is circular while all eukaroytes’ DNA is linear.

5. Movement
Unlike prokaryotes, eukaryotes have a nucleus that controls most cell functions. Eukaryotic cells also contain organelles, specialized subunits of a cell that have specific functions, such as making energy or communicating with other cells.
For example, mitochondria are organelles in your body’s cells that produce energy for you to use. This movement between organelles is what allows animal cells to move around your body, digest food, and contract muscles.
This article looked at the five biggest differences between prokaryotic and eukaryotic cells. By understanding the differences between these two types of cells, you can better understand how they work and what role they play in the body.
