In , Robert Hook discovered a cell. Some cells have membrane-bound organelles and some do not have. Depending upon the internal structure of the cell, two types of cells are found in an organism namely Eukaryotic and Prokaryotic.
What is the difference between Prokaryotic and Eukaryotic Cells?
A prokaryote is a cellular organism that lacks an envelope -enclosed nucleus. Organisms with nuclei are placed in a third domain, Eukaryota. Prokaryotes lack mitochondria , or any other eukaryotic membrane-bound organelles ; and it was once thought that prokaryotes lacked cellular compartments , and therefore all cellular components within the cytoplasm were unenclosed, except for an outer cell membrane. But bacterial microcompartments , which are thought to be primitive organelles enclosed in protein shells, have been discovered,   along with other prokaryotic organelles. Others, such as myxobacteria , have multicellular stages in their life cycles. Molecular studies have provided insight into the evolution and interrelationships of the three domains of life.
Depending on the internal structure of cell, organisms are divided into two types i. Prokaryotic organism are those which lacks true nucleus and membrane bound cell organelles. Eukaryotic organisms are those organisms which have true nucleus with nuclear and nucleolus and also contain all membrane bound cell organelles. Contain part of respiration and in some photosynthetic machinery. Sterol and carbohydrate is present that serve as receptors. Do not carry out respiration and photosynthesis. Glycocalyx Present as a capsule or slime layer.

Prokaryotic cells do not have a well-defined nucleus but DNA molecule is located in the cell, termed as nucleoid , whereas eukaryotic cells have a well-defined nucleus , where genetic material is stored. Based on the structure and functions, cells are broadly classified as Prokaryotic cell and Eukaryotic cell. Prokaryotic Cells are the most primitive kind of cells and lack few features as compared to the eukaryotic cell. Eukaryotic cells have evolved from prokaryotic cells only but contain different types of organelles like Endoplasmic reticulum, Golgi body, Mitochondria etc, which are specific in their functions. But features like growth, response, and most importantly giving birth to the young ones are the commonly shared by all living organisms.
Humans are home to around trillion bacterial cells meaning our bodies are like an ecosystem. An example of where living organisms can be found on humans can be the surface of our skin or in our digestive tract. Our bodies can contain both prokaryotic and eukaryotic cells. These type of cells are the major two divisions of cells. Organisms with Prokaryotic cells are called Prokaryotes, and organisms with Eukaroytic cells are called Eukaryotes. Prokaryotic cells are one of the categories of cells.
Prokaryotic cells are smaller and simpler than eukaryotic cells, and do not have a nucleus. Prokaryote = "before carrier bag" i.e. without a nucleus. Eukaryote = ".
Difference Between Prokaryotic Cells and Eukaryotic Cells
For those that didn't know, there are many similarities between prokaryotic and eukaryotic cells. These are two types of cells that make up living organisms, and this article will cover all the parallelism between them. The basic unit of life is cell. Living organisms are divided into two groups on the basis of their cellular structure: prokaryotes and eukaryotes. The former evolved 2 billion years before the evolution of latter.
