Fungi have complex carbohydrate cell walls (chitin, glucan, mannan) and can gram stain positive. Parasites lack cell walls, prions are proteins, and prokaryotes have peptidoglycan cell walls.
Fungi possess a complex carbohydrate cell wall (chitin, glucan, or mannan) and can retain Gram stain like Gram-positive bacteria due to their thick cell walls. Parasites lack cell walls, prions are infectious proteins, and prokaryotes have peptidoglycan cell walls.
| Front | What organism has a complex carbohydrate cell well but can gram stain as well? |
|---|---|
| Back | Complex carbohydrate cell wall (chitin, glucan or mannan) defines the organism as a fungus Gram stain can also be used diagnostically to differentiate some fungi as their thick cell wall makes them retain the gram stain just like gram (+) bacteria Parasites → no cell wall Prions → infectious proteins Prokaryotes → peptidoglycan cell wall Viruses → acellular |
