Study Notes
Cell Characteristics
- The cell is the fundamental unit of all living organisms, serving as the basic structural, functional, and biological unit.
Cell Types
- There are two primary types of cells: prokaryotic and eukaryotic.
Prokaryotic Cells
- Lack a nucleus, and their genetic material (DNA) is found in a nuclear area within the cell.
- Are smaller and simpler in structure compared to eukaryotic cells.
- Do not possess membrane-bound cell organelles, such as a nucleus.
- Reproduce through binary fission.
- Examples include bacteria and Archaea.
