Study Notes
Cell Characteristics
- Bacterial cells are called 'prokaryotic' because they have very little visible internal organization.
- The term 'prokaryotic' comes from Greek, meaning "before nucleus" or "primitive nucleus".
- Prokaryotic cells have genetic material free within the cell and lack visible internal organization.
Cell Structure and Shape
- Some cells have no defined geometric shapes.
- Cells with flexible boundaries are referred to as 'amoeboid'.
Cell Size
- The vast majority of bacterial cells are 10-20 µm in length.
Cell Types
- There are two main types of cells mentioned in the text: prokaryotic and (implicitly) eukaryotic.
Cell Features
- Bacterial cells are often described as having no obvious coloration.
- All cells exhibit a staggering diversity in terms of their characteristics and behaviors.
