原核的

無細胞核的

used in biology to describe a single-celled living thing whose cells have no nucleus — for example, bacteria. A prokaryotic cell's DNA floats freely inside the cell rather than being kept in a separate central compartment.

❌The old computer has a prokaryotic design.
✅The old computer has a simple design.
💡'prokaryotic' is a biology term for cells without a nucleus, not a general word meaning 'simple.'
❌Yeast is a prokaryotic organism.
✅Yeast is a eukaryotic organism.
💡yeast is a fungus, and fungi have a nucleus, so they are eukaryotic, not prokaryotic.
