Difference Between Prokaryotic and Eukaryotic Cells

Eukaryotic and Prokaryotic

Hey guys, welcome to this mometrix video on Eukaryotic and prokaryotic cells.

In this video we will take a look at what each are, and how they are different.

Eukaryotes:

Eukaryotes can be defined as any organism that has a cell or cells that are complex; more specifically, they have a membrane bound nucleus where all their genetic information is stored. The nucleus is not the only organelle contained within a eukaryotic cell membrane, but a membrane bound nucleus is unique to eukaryotes. All of the eukaryotic cell’s DNA is linear, and is stored within the nucleus. Eukaryotes can contain several other membrane bound organelles like: a golgi apparatus, endoplasmic reticulum, mitochondrion, and so on! Eukaryotic cells are large cells generally between 10-100 micrometers.

Guess what? You are a eukaryote, and all the cells that make you up are eukaryotic.

Some other examples of eukaryotes include: protists’, fungi, plants, and animals.

Prokaryotes:

Prokaryotic cells, on the other hand, are not quite as complex as eukaryotic cells. A prokaryote is a non-complex, single-celled organism that does not contain a nucleus, nor does it contain any membrane-bound organelles. It’s important to note that eukaryotes can be unicellular as well, but a prokaryote will is always unicellular. All of a prokaryote’s DNA is circular shaped, and floats freely within the cytoplasm of the cell. Prokaryotes are much smaller than eukaryotes; they range in size from 1 to 5 micrometers.

Examples of prokaryotes include bacteria, and archaea.
