what structure is present in both plant and yeast cells, but not in a bacterial cell?

The structure present in both plant and yeast cells but not in bacterial cells is the nucleus.

Why the nucleus is the answer

• Plant cells and yeast cells are eukaryotic , meaning they have a membrane‑bound nucleus that houses their DNA.

• Bacterial cells are prokaryotic , so their DNA floats freely in the cytoplasm and they lack a true nucleus.

Quick comparison table

Cell type	Nucleus present?	Cell type group
Plant cell	Yes	Eukaryotic
Yeast cell	Yes	Eukaryotic (fungus)
Bacterial cell	No	Prokaryotic

So in exam‑style questions, the expected answer to “what structure is present in both plant and yeast cells but not in a bacterial cell?” is the **nucleus**.
