Found on some bacteria; they enable the bacteria to adhere to surfaces A. pili B. capsules C. cilia D. prokaryotic flagella E. eukaryotic flagella

A

Some bacteria stain Gram-positive and others stain Gram-negative as a result of differences in the structure of their: A. cell wall B. ribosomes C. cell membrane D. capsule

A

The sites of protein synthesis in prokaryotic cells. A. ribosomes B. plastids C. Golgi complex D. endoplasmic reticulum E. mitochondria

A

Found in prokaryotic cells as well as eukaryotic cells. A. mitochondria B. ribosomes C. plastids D. endoplasmic reticulum E. Golgi complex

B

Of the following, which one is not found in prokaryotic cells? A. plasmids B. mitochondria C. cell membrane D. chromosome

B

Membrane-bound organelles where energy is produced by the Krebs cycle and electron transport chain. A. Golgi complex B. endoplasmic reticulum C. plastids D. mitochondria E. ribosomes

D
