Why is the number of prokaryotic species still unknown?

  1. They evolve too slowly to tell apart
  2. Many cannot be grown in laboratories
  3. They live only in the deep oceans
  4. They have no distinct cell membrane
Show answer and solution

Correct answer: B. Many cannot be grown in laboratories

Conventional taxonomy fails for microbes and many prokaryotes simply cannot be cultured in the lab.
