Question

select all of the following that correctly describe archaean cells.

□ most have cell walls
□ lack organelles
□ possess a nucleus
□ can have flagella
□ are larger than most eukaryotic cells

need help? review these concept resources.

Explanation:

1. Most have cell walls: Archaean cells, like many prokaryotes, most have cell walls (though their composition differs from bacteria).
2. Lack organelles: Archaea are prokaryotes, so they lack membrane - bound organelles.
3. Possess a nucleus: Archaea are prokaryotes and do not have a nucleus (nucleus is a feature of eukaryotes), so this is incorrect.
4. Can have flagella: Some Archaean cells can have flagella for motility.
5. Are larger than most eukaryotic cells: Eukaryotic cells are generally larger than prokaryotic (including Archaean) cells, so this is incorrect.

Answer:

• most have cell walls
• lack organelles
• can have flagella
