- Cell is the basic unit of life.
- Cells are important for an organism's survival.
Types of Cells
- There are two main types of cells: prokaryotic and eukaryotic cells.
Prokaryotic Cells
- Characterized by the absence of a true nucleus.
- Examples of prokaryotic cells include bacteria and archaea.
Eukaryotic Cells
- Defined as cells containing an organized nucleus and organelles enveloped by membrane-bound organelles.
- Examples of eukaryotic cells include animals, plants, fungi, and protists.
Cell Theory
