Fact 1: Prokaryotes are single-celled organisms that lack a nucleus.

Fact 2: Prokaryotes have no membrane-bound organelles, thus bacteria are prokaryotic organisms.

Given the two facts above, answer the question "bacteria have no membrane-bound organelles and lack what?" with the following options: 
- nucleus
 - epidermal
 - Joules
 - alveoli
 - glucose
 - Epidermis
 - oxygen
