Cells are the basic structural and functional unit of life. The term cells were first coined in 1665 by British scientist Robert Hooke. He was the first person to study living things under a microscope, examine a thin slice of cork under a microscope, and observe honeycomb-like structures. Robert Hooke called these structures cells.
Types of cells
There are basically two types of cells in an organism. The two types of cells are listed below.
- Prokaryotic cells
- Eukaryotic cells
The difference between Prokaryotic cells and Eukaryotic cells are listed below
|Organisms are always unicellular||Organisms are always unicellular and multicellular.|
|Nucleus is absent||Nucleus is present|
|Cell division takes place through binary fission||Cell division takes place through mitosis|
|DNA arrangement is circular||DNA arrangement is linear|
|Example: Bacteria, Blue-green algae||Example: Plant and animal cell|
