Misconceptions categories
Undergeneralization
- Bacteria live in solitary and colony (no detail explanations and no images.
- Bacteria have cell walls and generally have non-chlorophyll cell walls (no images).
- Sexual reproduction is in form of transformation, transduction, and conjugation which are briefly described using images without giving further explanation about the images.
- Bacterial decomposers (saprobe) denitrify dead plants/animals, as well as organisms’ residual / feces.
Oversimplification
- Bacteria are unicellular and consist of one cell (no images).
- Bacteria are prokaryotic (have no nucleus membrane).
- Classification of gram-positive and negative bacteria is based on differences in polypeptide thickness.
Overgeneralization
- Additional bacterial structures are in the form of endospore
Misidentification
Flagella are whip feathers composed of protein compounds, located on the cell wall.
