You are presented with the question "bacteria have no membrane-bound organelles and lack what?" and the following answer choices: 
- nucleus
 - epidermal
 - Joules
 - alveoli
 - glucose
 - Epidermis
 - oxygen
 - PDAs

Now knowing that prokaryotes are single-celled organisms that lack a nucleus and prokaryotes have no membrane-bound organelles, thus bacteria are prokaryotic organisms, choose the best answer.
