Bacterial Cell Diagram Labeling Worksheet

This bacterial cell labeling worksheet gives your students focused practice identifying the structures of a prokaryotic cell on a clear, accurate diagram. Using the word bank, students label seven numbered parts: the flagellum, pili, cell wall, cell membrane, cytoplasm, DNA (nucleoid), and ribosomes.

The diagram highlights exactly what makes bacteria different from plant and animal cells — no nucleus, no membrane-bound organelles, DNA coiled freely in the cytoplasm — making this a natural companion to any prokaryotic vs. eukaryotic cells lesson. Numbered callout lines point precisely at each structure, so students connect the term to the actual location instead of guessing.

What’s included (3 pages):

• Full-color labeling worksheet with word bank
• Ink-friendly black-and-white version of the same worksheet
• Complete answer key

Perfect for: introducing cell structure, microorganisms and bacteria units, review before a cells quiz, sub plans, interactive notebooks, or quick formative assessment in grades 6–8 life science. Supports NGSS MS-LS1-2. Print and go — no prep required.
