What a major characteristics distinguish eubacteria from protista?

Answer 1

Eubacteria are prokaryotic, meaning that they lack a nucleus or organelles bound to the membrane. Protists are eukaryotic, meaning that they do have the nucleus.

Answer 2

Eubacteria are prokaryotic organisms with a simple cell structure lacking a nucleus, while protists are eukaryotic organisms with a more complex cell structure containing a nucleus. Eubacteria are typically unicellular and lack membrane-bound organelles, whereas protists can be unicellular or multicellular and often have specialized organelles for specific functions. Additionally, eubacteria have a rigid cell wall made of peptidoglycan, while protists generally do not have a rigid cell wall.

Answer 3

The nucleus.
