常见错误

❌ 错误:Prokaryote is a kind of virus.
✓ 正确:Prokaryote is a type of cell or organism, such as bacteria.

错误地将原核生物归类为病毒;原核生物是细胞生物(如细菌),而病毒是非细胞结构,两者不同。

❌ 错误:All prokaryotes are harmful to humans.
✓ 正确:Many prokaryotes are beneficial, like those in gut flora.

误以为所有原核生物都有害;实际上,许多原核生物(如肠道菌群)对人类有益,只有部分致病。

近义词辨析

bacteria

细菌是原核生物的一个主要类别,但原核生物还包括古菌;细菌更具体,原核生物更泛指。

Bacteria are prokaryotes, but not all prokaryotes are bacteria (some are archaea).

microorganism

微生物包括原核生物、真核生物(如真菌)等更广范围;原核生物特指没有细胞核的单细胞生物。

Prokaryotes are a subset of microorganisms, which also include eukaryotes like yeast.
